A San Francisco-based R&B band originally formed by guitarist Larry Field as the New Invaders in the wake of the Summer of Love, Cold Blood had the key elements of strong female vocalist, a fine guitarist, and a powerful horn section. After successful gigs at Golden Gate Park and at the Fillmore, they were signed by impresario Bill Graham to his new San Francisco Records label, on which they released their self-titled debut in 1969. Four more albums followed over the next five years — in fact, later efforts boasted the production and musical contributions of Steve Cropper — but all were hamstrung by Grahams underhanded distribution deals with Columbia and Atlantic.
