The inimitable Bobby Ace played guitar alongside Jerry Garcia for over three decades. His unique style and merry personality helped shape the sound and spirit of the Grateful Dead, and his lifelong dedication to the band helped make them immortal.

Bob Weir's guitar playing made an indelible contribution to the Grateful Dead. It may have been even more radical than you think.

"I'll meet you in the music. Come find me anytime," said Connecticut's John Mayer about his Dead & Company bandmate.

On "Anthem of the Sun," the Dead's second studio album, Weir had already begun to stretch himself as a singer and as a songwriter. Authoring this noisy, jazzy track all by his lonesome, Weir vocally zig-zagged his way across a cluttered arrangement flush with oddball time changes.
