Filled with hypnotic bass lines, heavy drums and screaming fuzz guitars "Underground", the first LP of the fictitious group known as Braen's Machine, is one of the rarest and the most expensive of them all, always "reaching" sky high prices throughout the second hand vinyl market. Fast-beat jams with hammond scales and twin lead guitars! The pieces found on this collection were culled from thousands of recording sessions that took place at Umiliani's studios in the early Seventies for the purpose of being used in films, and the all-instrumental `Underground' from 1971 is assortment of cool grooving acid rock improvisations, trippy psychedelic jams and sound-collage experimentations that is sure to be of interest to collectors of both film scores of the period and the early movements of the artier Italian rock bands of that decade.
