Thomas & Richard Frost (born Thomas Martin and Richard Martin) were members of several San Mateo, CA-based groups during the early to mid-'60s -- including a surf group (the Impressions), a folk-rock group (the Newcastle Five), and a fuzz rock group (the Art Collection, teaming up with visiting New Zealand singer Ray Columbus) -- before forming a mod-pop power trio called Powder. This group moved down to L.A. to record an album at Hollywood's Gold Star studios, and while they were there also found employment as Sonny & Cher's touring group. Despite hailing from Northern California, their pop art-psychedelic singles were the closest thing the West Coast to rival swinging London's early Who and the Creation. Unfortunately for the brothers Martin, Powder's LP was never released. Discouraged, they returned to San Mateo, but it wasn't long before they were recording new material again, this on their own. They soon attracted the attention of Imperial Records, who signed the duo, who were now calling themselves Thomas & Richard Frost.
