In the vast array of bodies and souls that form that what is rock and roll identify irreplaceables.
John Lennon Jimi Hendrix all of Led Zeppelin your turn who do you think?
Moderator Edit: Edited title for clarity
@Thrasyic great choices, especially Led Zeppelin.
CCR, Janice Joplin, Bob Dylan, Elvis, Bruce Springsteen, Joe Cocker, Van Halen (David Lee Roth), Guns 'N' Roses, Deep Purple, The Black Crowes, and Pink Floyd, even though Pink Floyd's music was mostly psychedelic they were still ranked amongst some of the best.
Take care and GOD bless.
