American rock band, Grateful Dead, emerged from the San Fransisco bay area in 1965 fusing many different types of music to become one of the best-loved bands of that era.
They were ranked 55th in the issue: ''Greatest Artists of All Time'' by Rolling Stone magazine and were comprised of Jerry Garcia (lead guitarist) also a reluctant leader, Phil Lesh (bass), Bob Weir ( rhythm guitar), Ron 'Pigpen' McKernon (keyboards/harmonica) and Bill Kreutzman (drums).
The line-up changed over their 30 year history, but with the exception of McKernon the core stayed the same until Garcia, a charismatic man with a tendency to self-destruction - obesity and drug abuse - died.
Eleven members of Grateful Dead were inducted into the Rock n Roll Hall of Fame in 1994. Their early music was seen as an interpretation of psychedelia, and they gained commercial success with ''Workingman's Dead'' and ''American Beauty''.
The band were well-known for their gargantuan touring - with 2,300 live concerts under their belts in three decades, no wonder their fans - the Deadheads - were so devoted.
In 2008 the Grateful Dead put on two concerts for president Obama entitled "Change Rocks" and "Deadheads for Obama", the Grateful Dead have decided to re-unite and tour in 2009.
