I got this off discogs, ironically enough the seller didn't mention it was a promo copy. This also has WQSR written on the labels and front. WQSR was a Quadraphonic station in Sarasota! So it appears I have a quad copy of Santana and Alice Coltrane Illuminations that belonged to a quad radio station. Cool piece of history if you ask me. Did anyone listen to this station?
From Wikipedia: During part of this period, the station added quadraphonic sound, and promoted itself as "Quad One-Oh-Two-And-A-Half". The free-form music format would eventually suffer challenges from other formats that eroded its Arbitron ratings in the critical 25-34 and 25-54 demographics.
