(3-CD set) 3 CD Box Set packaged in a DVD size 8 panel format with 20 page full color booklet, detailed liner notes, an essay by Malcolm Morley From Help Yourself. Limited to 500 copies. Convolutions Of The Brain gathers together 49 songs, four hours of unreleased studio recordings, rare compilation tracks, film music, live performances, and remixed album tracks recorded between 1991 and 2017. The centerpiece of the three-disc set is the Seattle Terrastock Festival rehearsal sessions with Richard Treece. Donovan's Brain has never been shy about showing their many facets. They are equally comfortable with multi-colored psych, jangly pop, extended West Coast guitar excursions, straight ahead rock, and synth experiments. An extended cast that includes long time partners Deniz Tek and Bobby Sutliff assists Main Brain Ron Sanchez. Guitarist Richard Treece (RIP) from the UK cult band Help Yourself is featured on half the songs. Help Yourself band mates Ken Whaley (RIP) and Malcolm Morley also appear. Journeyman rockers Dave Walker (Savoy Brown) and Ric Parnell (Spinal Tap) are also present. Every Brain line up is represented including the current band.
