The Rhythm Devils began as the duo of Grateful Dead drummer Bill Kreutzmann and his percussionist partner Mickey Hart. Over the years, they transcended rock and roll drum stereotypes with polyrhythmic explorations of the world of percussion, using an extraordinary variety of instruments and approaches. The aftermath of this collaboration was the larger Rhythm Devils, which have made periodic reappearances over the years. The 2010 version includes Bill Kreutzmann and Mickey Hart, Keller Williams (guitar, vocals) in July and Tim Bluhm of the Mother Hips (guitar, vocals) on later dates, Davy Knowles (guitar, vocals), Sikiru Adepoju (talking drum), and Andy Hess (bass). Together, they will take music beyond the horizon to a universe where rhythm is in constant flux and sound has infinite potential.
