The Paul Butterfield Blues Band

Bloomfield formed The Electric Flag with Nick Gravenites, and Bishop began playing lead guitar on The Resurrection of Pigboy Crabshaw (1967). The band now included saxophonists David Sanborn and Gene Dinwiddie, bassist Bugsy Maugh, and drummer Phillip Wilson. In 1967, The Butterfield Blues Band played the seminal Monterey International Pop Festival along with the Electric Flag, Jimi Hendrix, Ravi Shankar, The Who, Otis Redding, the counterculture bands of San Francisco, and many others. After the release of In My Own Dream, both Bishop and Naftalin left by the end of 1968. Nineteen-year-old guitarist Buzzy Feiten, joined the band for its 1969 release, Keep On Moving, produced by Jerry Ragavoy, and Rod Hicks replaced Maugh on bass. The Butterfield band played at the Woodstock Festival, although their performance wasn't included in the resulting Woodstock film. In 1969, Butterfield also took part in a concert at Chicago's Auditorium Theater and a subsequent recording session organized by record producer Norman Dayron, featuring Muddy Waters and backed by pianist Otis Spann, Michael Bloomfield, Sam Lay, Donald "Duck" Dunn, and Buddy Miles, which was recorded and portions released on Fathers And Sons on Chess Records.
