Bill Kreutzmann

While he may have been hidden behind a drum kit and the well-known frontmen of the Grateful Dead (perhaps only because they were stationed in front of him), Bill Kreutzmann spent 30 years stretching and surpassing the percussive limits of music as a drummer for the infamous jam band. Paired with drummer Mickey Hart, the two "Rhythm Devils" kept Deadheads spinning in time to the band's vast vault of tunes and their own creations. After the band's demise with Jerry Garcia's own in 1995, Kreutzmann has kept himself busy with plenty of projects.
