I purchased the Chicago and Doobie Brothers Quadio box sets. I love the quad mixes, the great quality and care taken with these Quadio sets. The pricing of the upcoming Quadio single releases is fantastic. That said, none of the artists being discussed for the upcoming Quad releases excite me much IMO. I would really like Randy Newman - Good Old Boys but beyond that title i don‘t see much left for me to purchase. Are the Paul Simon Quad mixes owned by Rhino? The Paul Simon Quad mixes I would buy. JMHO
