This piece of music from the Haskell Wexler film Medium Cool (starring Robert Forster), is brilliant and cool and down right impossible to find. Never fear, there is a clip of it on my music downloads (thanks to Jim's ingenious computer skills).
Otherwise, unless you hear the music by renting the movie (which you should rent anyway), this slick, urban western instrumental is lost in the wasteland of a forgotten film (despite Medium Cool's status as one of the most inventive and influential films of the decade, it rarely gets a mention today) and an unreleased soundtrack.
Mike Bloomfield, who is Wexler's cousin, is primarily a blues man who enjoyed a very successful career with the The Paul Butterfield Blues Band, which played backup for Bob Dylan in 1967. After that he formed the seminal band Electric Flag before eventually retiring and becoming a recluse in San Fransisco.
