Forest (also known as Foresters of Walesby) was an English psychedelic-folk / acid-folk trio that formed in Grimsby, Lincolnshire, England, in 1966. Made up of brothers Martin Welham, Adrian Welham and school friend Dez Allenby, they started out performing unaccompanied traditional folk music in a similar vein to contemporaries The Watersons and The Young Tradition. The band were pioneers of the nascent 1960s underground acoustic-psychedelic/acid-folk scene writing unconventionally crafted songs evoking Britain’s ancient groves using a variety of acoustic instruments.
