The Eagles are definitely an amazing band, but as said here in a earlier thread, very overplayed over the years. I'd probably pass on a Rhino issue of them. I have the quad albums and rarely play them.
I'd absolutely love Carly Simon and Joni Mitchell. I definitely wouldn't mind the McCartney and Wings stuff that was out on Q8. Alice Cooper and Linda Ronstadt were both in the Warner family back in the day, too. They'd be great, but I don't think any of Linda's stuff ever made it to quad for some reason.
I missed out on the Chicago. Love them! I wasn't collecting yet when it came out, but I have most of their albums in quad. (SQ unfortunately
) It's definitely pricey now.
