The Electric Flag was an American blues/rock/soul band from Chicago, led by guitarist Mike Bloomfield, keyboardist Barry Goldberg and drummer Buddy Miles, and featuring other musicians such as vocalist Nick Gravenites and bassist Harvey Brooks. Bloomfield formed the Electric Flag in 1967, following his stint with the Butterfield Blues Band. The band reached its peak with the 1968 release, A Long Time Comin', a fusion of rock, jazz, and R&B styles that charted well in the Billboard Pop Albums chart. Their initial recording was a soundtrack for The Trip, a movie about an LSD experience by Peter Fonda, written by Jack Nicholson and directed by Roger Corman.

Michael Bernard Bloomfield was an American blues guitarist and composer. Born in Chicago, he became one of the first popular music stars of the 1960s to earn his reputation almost entirely on his instrumental prowess, as he rarely sang before 1969. Respected for his guitar playing, Bloomfield knew and played with many of Chicago's blues musicians before achieving his own fame and was instrumental in popularizing blues music in the mid-1960s. In 1965, he played on Bob Dylan's Highway 61 Revisited, including the single "Like a Rolling Stone", and performed with Dylan at that year's Newport Folk Festival.
