Milestones

DIED. Paul Butterfield, 44, innovative harmonica player of the 1960s and co- founder of the Paul Butterfield Blues Band, which helped introduce city blues to rock audiences; of undetermined causes; in Los Angeles. The band backed Bob Dylan when he used an electric guitar, a controversial move, at the 1965 Newport Folk Festival, but became celebrated in its own right for cleverly merging blues, rock, folk and jazz themes.
