"Latest offering in our series of Christian titles, this time from those noted style gurus, McDonald & Sherby, whose sole contribution to the canon of 20th century music was Catharsis, an album which originally appeared on the appropriately-named Omniscient label (Omniscient Records 1426S) Some have speculated that given the band's prog/psych leanings, Catharsis was probably recorded in the '70s, although the accepted wisdom is that the album was made at Minneapolis's Sound 80 Studios on 1969. The album consists of six long tracks with a decidedly heavy guitar-based vibe, all well- recorded and delivered with considerable aplomb. A guitar-based progressive album recorded at Sound 80 in Minneapolis. Though undated, the record sounds of a mid-seventies vintage, not dissimilar to fellow Great Lakes prog rockers Kopperfield."
