Horse were an early hard rock/proto-metal band from London, formed in 1968 by singer Adrian Hawkins and guitarist Rod Roach. Together with bassist Colin Standring and Rick Parnell on drums, they began writing songs. They toured the London pub and club scene, sharing the stage with greats such as Deep Purple and David Bowie, and soon built up a large fan base thanks to their exciting live performances. Their dark and aggressive heavy psychedelic rock, characterised by Adrian Hawkins’ powerful growling vocals and Rod Roach’s furious fuzz-wah guitar playing, attracted the interest of several record companies.

After finally signing a contract with the major label RCA, they recorded their first and only album at Olympic Sound Studios. Produced by Rod Roach, it was released in June 1970 with a front cover design by Roger Wootton, the singer and songwriter of the band Comus. As it was a commercial failure, RCA terminated the record contract. However, the lack of support from the record company soon led to their dissolution. This legendary, self-titled debut album is now considered one of the rarest hard rock albums of its era, with original copies from the UK now fetching astronomical prices.
