The Grateful Dead was an American rock band formed in 1965 in San Francisco, California. Known for their unique blend of rock, folk, blues, and jazz, they became a key part of the counterculture movement of the 1960s. The band's improvisational style and long live performances attracted a dedicated fan base, often referred to as "Deadheads." The Grateful Dead's lineup included iconic members such as Jerry Garcia, Bob Weir, and Phil Lesh. They released several influential albums, including "American Beauty" and "Workingman's Dead." The band continued to perform until Garcia's death in 1995, leaving a lasting legacy in the music world.
