In 1963, he formed the Paul Butterfield Blues Band, which recorded several successful albums and was popular on the late-1960s concert and festival circuit, with performances at the Fillmore West in San Francisco, the Fillmore East in New York City, the Monterey Pop Festival, and Woodstock. The band was known for combining electric Chicago blues with a rock urgency and for their pioneering jazz fusion performances and recordings. After the breakup of the group in 1971, Butterfield continued to tour and record with the band Paul Butterfield's Better Days, with his mentor Muddy Waters, and with members of the roots-rock group the Band. While still recording and performing, Butterfield died in 1987 at age 44 of an accidental drug overdose.
