Previously unknown, Acid-Archives worthy, private press, basement hardrock / prog from mid-Seventies Chicago! "THE CHICAGO TRIANGLE is a flock of the rarest birds: a Latino hard rock quartet, emerging from Chicago's near-north side, and also harboring an arcane interest in the mysticism of the triangle. Although it was released in 1977, it could have been 1969, or 1989, or 2015… in any decade, it was destined for deepest obscurity, and is now of most profound interest."—Rob Sevier, Numero Group. Limited edition of 200 black vinyl copies.
