Keyboardist Colin Catt and bassist Phil Gunn had known each other from college since the mid-60s. Together with Paul Young (drums), they began to play jam sessions, which were then joined by various guitarists. Inspired by Cream, they gradually incorporated elements of blues and jazz into their R&B style. After returning from a concert tour in Germany in 1969, they signed a recording contract with the small Evolution label as the five-piece band Raw Material with guitarist Dave Green and Mike Fletcher (sax, fl, harm, voc). In 1970 they recorded their self-titled debut LP, which was released in the same year. They played a prog rock with a dominating organ, earthy-bluesy hard rock, which was enhanced by occasional flute and saxophone interludes in the direction of jazz.
Due to a lack of promotion and the complete ignorance of the press, this album was doomed to failure right from the start. Nowadays, Evolution Records originals fetch a small fortune on the collectors' market. A year later, they recorded their second album Time Is... which is also a rarity as an original on RCA Neon.
