"感恩而死"乐队是"旧金山声音"的典型代表。它的创立人和中心人物是杰里·加西亚（Jerry Garcia，1942～1995），生于旧金山，15岁在中学时学习吉他。60年代初，他被蓝草音乐（Bluegrass Music）所吸引，有时也在咖啡馆里演出这种音乐。1963年，他组织了一个"罐筒"乐队，到1965年已有五人参加，开始用电声乐器演奏。1966年，他们在旧金山的海特-阿什伯利地区与其他人一起过着公社式的生活，给乐队取名?quot;感恩而死"；因受"披头士热"的影响，改而演奏摇滚乐。60年代中期，海特-阿什伯利地区经常举行自由聚会，进行药物试验（acid test），用药者可以进入从错觉到幻觉各种知觉变化状态。伴随着吸毒场面，不可缺少的景象是奇异的穿着和声音很大的摇滚乐。正是在这样的氛围中，"感恩而死"进行了自由的音乐实验。与此同时，他们也经常进行同样的带有实验性的音乐演出。他们的声音越来越大、越来越强劲、有更多的即兴、没有固定的形式，时间也变得更长。他们利用电子手段产生的声音，如反馈、失真、颤音效果等，都受到听众的欢迎。 1966年，"感恩而死"与华纳兄弟（Warner Brother）唱片公司签约，发行了他们第一张专辑《感恩而死》（The Grateful Dead），于1967年获专辑排行榜第73名。他们习惯在与听众交流的情况下，自由自在地在现场演出，而不习惯在录音棚里工作。他们重视现场演出，曾经开过连续演奏5个小时的音乐会、免费音乐会，甚至自己出资50万，带了器材（于1978年）到埃及金字塔下举行义演。60年代末，"感恩而死"推出的专辑有《太阳颂歌》（Anthem the Sun，1968）、《Aoxomoxoa》（1969）以及根据现场演出录音制成的《生死》（Live /Dead ，1969）。70年代初，"感恩而死"的风格变得简明，并带有明显的乡村音乐成分，如《工人之死》（Workingman 's Dead 1970）和《美国的美》（American Beauty，1970）。在这些作品中，加西亚采用原声吉他代替电声吉他，表明乐队离开了60年代末的迷幻摇滚风格。后来的专辑风格更加多样化，如《为真主的布鲁斯》（Blues for Allah1975）带有爵士影响；《龟鳖栖身地》（Terrapin Station，1977）使用了圆号、弦乐和合唱。另外，"感恩而死"的成员们在70年代大都已停止使用LSD。尽管如此，在听众的心目中，他们仍然是迷幻文化的代表，他们表现出来的某种神话般的魅力，仍然吸引了新一代的乐迷们。Rock's longest, strangest trip, the Grateful Dead were the psychedelic era's most beloved musical ambassadors as well as its most enduring survivors, spreading their message of peace, love, and mind-expansion across the globe throughout the better part of three decades. The object of adoration for popular music's most fervent and celebrated fan following — the Deadheads, their numbers and devotion legendary in their own right — they were the ultimate cult band, creating a self-styled universe all their own; for the better part of their career orbiting well outside of the mainstream, the Dead became superstars solely on their own terms, tie-dyed pied pipers whose epic, free-form live shows were rites of passage for an extended family of listeners who knew no cultural boundaries.The roots of the Grateful Dead lie with singer/songwriter Jerry Garcia, a longtime bluegrass enthusiast who began playing the guitar at age 15. Upon relocating to Palo Alto, CA, in 1960, he soon befriended Robert Hunter, whose lyrics later graced many of Garcia's most famous melodies; in time, he also came into contact with aspiring electronic music composer Phil Lesh. By 1962, Garcia was playing banjo in a variety of local folk and bluegrass outfits, two years later forming Mother McCree's Uptown Jug Champions with guitarist Bob Weir and keyboardist Ron "Pigpen" McKernan; in 1965, the group was renamed the Warlocks, their lineup now additionally including Lesh on bass as well as Bill Kreutzmann on drums. The Warlocks made their electric debut that July; Ken Kesey soon tapped them to become the house band at his notorious Acid Tests, a series of now-legendary public LSD parties and multimedia "happenings" mounted prior to the drug's criminalization. As 1965 drew to its close, the Warlocks rechristened themselves the Grateful Dead, the name taken from a folk tale discovered in a dictionary by Garcia; bankrolled by chemist/LSD manufacturer Owsley Stanley, the band members soon moved into a communal house situated at 710 Ashbury Street in San Francisco, becoming a fixture on the local music scene and building a large fan base on the strength of their many free concerts. Signing to MGM, in 1966 the Dead also recorded their first demos; the sessions proved disastrous, and the label dropped the group a short time later. As 1967 mutated into the Summer of Love, the Dead emerged as one of the top draws on the Bay Area music scene, honing an eclectic repertoire influenced by folk, country, and the blues while regularly appearing at top local venues including the Fillmore Auditorium, the Avalon Ballroom, and the Carousel. In March of 1967 the Dead issued their self-titled Warner Bros. debut LP, a disappointing effort which failed to recapture the cosmic sprawl of their live appearances; after performing at the Monterey Pop Festival, the group expanded to a six-piece with the addition of second drummer Mickey Hart. Their follow-up, 1968's Anthem of the Sun, fared better in documenting the free-form jam aesthetic of their concerts, but after completing 1969's Aoxomoxoa, their penchant for time-consuming studio experimentation left them over 100,000 dollars in debt to the label. The Dead's response to the situation was to bow to the demands of fans and record their first live album, 1969's Live/Dead; highlighted by a rendition of Garcia's "Dark Star" clocking in at over 23 minutes, the LP succeeded where its studio predecessors failed in capturing the true essence of the group in all of their improvisational, psychedelicized glory. It was followed by a pair of classic 1970 studio efforts, Workingman's Dead and American Beauty; recorded in homage to the group's country and folk roots, the two albums remained the cornerstone of the Dead's live repertoire for years to follow, with its most popular songs — "Uncle John's Band," "Casey Jones," "Sugar Magnolia," and "Truckin'" among them — becoming major favorites on FM radio. Despite increasing radio airplay and respectable album sales, the Dead remained first and foremost a live act, and as their popularity grew across the world they expanded their touring schedule, taking to the road for much of each year. As more and more of their psychedelic-era contemporaries ceased to exist, the group continued attracting greater numbers of fans to their shows, many of them following the Dead across the country; dubbed "Deadheads," these fans became notorious for their adherence to tie-dyed fashions and excessive drug use, their traveling circus ultimately becoming as much the focal point of concert dates as the music itself. Shows were also extensively bootlegged, and not surprisingly the Dead closed out their Warners contract with back-to-back concert LPs — a 1971 eponymous effort and 1972's Europe '72. The latter release was the final Dead album to feature Pigpen McKernan, a heavy drinker who died of liver failure on March 8, 1973; his replacement was keyboardist Keith Godchaux, who brought with him wife Donna Jean to sing backing vocals. 1973's Wake of the Flood was the first release on the new Grateful Dead Records imprint; around the time of its follow-up, 1974's Grateful Dead From the Mars Hotel, the group took a hiatus from the road to allow its members the opportunity to pursue solo projects. After returning to the live arena with a 1976 tour, the Dead signed to Arista to release Terrapin Station, the first in a series of misguided studio efforts that culminated in 1980's Go to Heaven, widely considered the weakest record in the group's catalog — so weak, in fact, that they did not re-enter the studio for another seven years.The early '80s was a time of considerable upheaval for the Dead — the Godchauxs had been dismissed from the lineup in 1979, with Keith dying in a car crash on July 23, 1980. (His replacement was keyboardist Brent Mydland.) After a pair of 1981 live LPs, Reckoning and Dead Set, the group released no new recordings until 1987, focusing instead on their touring schedule — despite the dearth of new releases, the Dead continued selling out live dates, now playing to audiences which spanned generations. As much a cottage industry as a band, they traveled not only with an enormous road crew but also dozens of friends and family members, many of them Dead staffers complete with health insurance and other benefits. Still, the Dead were widely regarded as little more than an enduring cult phenomenon prior to the release of 1987's In the Dark; their first studio LP since Go to Heaven, it became the year's most unlikely hit when the single "Touch of Grey" became the first-ever Dead track to reach the Top Ten on the pop charts. Suddenly their videos were in regular rotation on MTV, and virtually overnight the ranks of the Deadheads grew exponentially, with countless new fans flocking to the group's shows. Not only did concert tickets become increasingly tough to come by for longtime followers, but there were also more serious repercussions — the influx of new fans shifted the crowd dynamic considerably, and once-mellow audiences became infamous not only for their excessive drug habits but also for their violent encounters with police. Other troubles plagued the Dead as well: in July 1986, Garcia — a year removed from a drug treatment program — lapsed into near-fatal diabetic coma brought on by his continued substance abuse problems, regaining consciousness five days later. His health remained an issue in the years which followed, but the Dead spent more time on tour than ever, with a series of dates with Bob Dylan yielding the live album Dylan & the Dead. Their final studio effort, Built to Last, followed in 1989. Tragedy struck in October of that year when a fan died after breaking his neck outside of a show at the New Jersey Meadowlands; two months later, a 19-year-old fan on LSD also died while in police custody at the Los Angeles Forum.As ever, the Dead themselves were also not immune to tragedy — on July 26, 1990, Mydland suffered a fatal drug overdose, the third keyboardist in group history to perish; he was replaced not only by ex-Tubes keyboardist Vince Welnick but also by satellite member Bruce Hornsby, a longtime fan who frequently toured with the group. In the autumn of 1992 Garcia was again hospitalized with diabetes and an enlarged heart, forcing the Dead to postpone their upcoming tour until the year's end; he eventually returned to action looking more fit than he had in years. Still, few were surprised when it was announced on August 9, 1995, that Garcia had been found dead in his room at a substance abuse treatment facility in Forest Knolls, CA; the 53 year old's death was attributed to a heart attack. While Garcia's death spelled the end of the Dead as a continuing creative entity, the story was far from over. As the surviving members disbanded to plot their next move, the band's merchandising arm went into overdrive — in addition to Dick's Picks, a series of archival releases of classic live material, licensed products ranging from Dead T-shirts to sporting goods to toys flooded the market. Plans were also announced to build Terrapin Station, an interactive museum site. In 1996, Weir and Hart mounted the first Furthur Festival, a summer tour headlined by their respective bands RatDog and Mystery Box; in 1998, they also reunited with Lesh and Hornsby to tour as the Other Ones. In spirit if not in name, the Grateful Dead's trip continued on.
