According to AllMusic: "Prog-rock began to emerge out of the British psychedelic scene in 1967, specifically a strain of classical/symphonic rock led by the Nice, Procol Harum, and the Moody Blues ("Days of Future Passed")." The availability of newly affordable recording equipment coincided with the rise of a London underground scene at which the psychedelic drug LSD was commonly used. Pink Floyd and Soft Machine functioned as house bands at all-night events at locations such as Middle Earth and the UFO Club, where they experimented with sound textures and long-form songs. Many psychedelic, folk rock and early progressive bands were aided by exposure from BBC Radio 1 DJ John Peel. Jimi Hendrix, who rose to prominence in the London scene and recorded with a band of English musicians, initiated the trend towards guitar virtuosity and eccentricity in rock music. The Scottish band 1-2-3, later renamed Clouds, were formed in 1966 and began performing at London clubs a year later. According to "Mojo" George Knemeyer: "some claim they had a vital influence on prog-rockers such as Yes, The Nice and Family."
