Credited as one of the best late ’60s German psych-rock albums, Bokaj Retsiem’s (‘Meister Jakob’ in reverse) ‘Psychedelic Underground’ is an eccentric, soulful, acid and fuzzy rockin’ essay that clearly prefigures a part of the krautrock movement. Featuring Rainer Deigner, former guitarist for the ’60s German beat group German Bonds, as the only credited musician and composer on this album (although other musicians assisted him on bass, keyboards, and that B3 Hammond and Leslie sound), this is basically Rainer’s freaked-out tribute to his favourite children’s song, ‘Meister Jakob,’ consisting in trippy instrumental sections, furiously savage E-guitar crescendos, amazing psych-rock improvisation, with just a hint of ’60s US psych-garage. A real enthusiastic psych-kraut trip for fans of Vanilla Fudge, Hendrix and Iron Butterfly. Comes on 180 gram cyan blue vinyl.
