Like most of what is posted here. For reference I prefer music from instruments that don't plug into the wall, that you can actually hear the lyrics and that one does not jump up and down to listen to. That said, guitar is a favorite and Joe Pass wasn't mentioned. Great talent like Jim Hall.
Kind of Blue
This was the first Jazz CD I ever owned. I currently have over 200 Jazz CDs and Kind of Blue is still #1 on my list.
What are your favs?
