Butterfield Blues Band
The Paul Butterfield Blues Band was signed to Elektra Records after adding Bloomfield as lead guitarist.[2] Their original debut sessions were scrapped, to appear in 1995 as The Original Lost Elektra Sessions. A second attempt was recorded live at the Cafe Au Go Go, but these too were rejected by producer Paul Rothchild. Some of the discarded tracks appeared on the What's Shakin LP shared with the Lovin' Spoonful.
At the Newport Folk Festival in July 1965, Bob Dylan went electric in a move considered controversial at the time by much of the folk music establishment, backed by members of Butterfield's band — Bloomfield, Arnold, and Lay — but not Butterfield himself.[2] In October, the self-titled debut recorded a third time after the addition of organist Mark Naftalin on some tracks, The Paul Butterfield Blues Band, containing Nick Gravenites' "Born in Chicago," was released.[2] Shortly thereafter, Lay became ill with pneumonia and pleurisy and Billy Davenport took over on drums. The Butterfield Band's second album was East-West, released in 1966, after which Bloomfield, Arnold, and Davenport left the 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.http://en.wikipedia.org/wiki/Paul_Butterfield#Butterfield_Blues_Band
