I have been listening to the Eno/Bowie stuff for so long, I'm not sure I can be objective on the matter.
Actually I came to Eno through Bowie and Talking Heads. I had always heard the name, but it wasn't until I realized that he was involved in my favorites from these bands that I started picking up his stuff. I don't really listen to the Talking Heads that much anymore, although the pre-Let's Dance Bowie still gets an occasional spin.
Somehow I missed the Eno & Cale stuff, although that has already been rectified.
