After seeing this for a few years in my favorite record store in Ventura, calif I finally picked up the Evolution 4 channel music sampler and brought it home. Primarily for the one cut by Lighthouse. The other tracks are synthesizer Light pop covers on the cheezy side with lots of rear speaker action.
This record will probably disappear into my collection for the next 15 years....
I also picked up a Brahms piano concerto in SQ on the Connoisseur Society label (USA). These may originally be EMI recordings. I find that all the records I have on that label are very well recorded.
