Formed in the late '60s, these San Franciscans sounded like Tower of Power with Janis Joplin on lead vocals. In their songs, punchy horns and organ jabs ride over some exceptionally tight funk drumming, with everything centered around the soulful wails of Lydia Pense. Guest artists such as the Pointer Sisters helped enhance the sound, but Cold Blood never had the hit they needed to break out. Rumored to be reunited.
