Pink Moon. My favorite of his albums, it's somewhat slight but gorgeous.
Behaviour. I'd put this second to Introspective but it's still great, even if it's sometimes a little more sedate than I'm in the mood for.
Younger Than Yesterday. I don't get why this is often considered their best album - I think it's the weakest of their first five - but it's still got a couple great little songs ("Time Between", "The Girl With No Name") in between some of the more ponderous stuff like "Renaissance Fair" and "Mind Gardens".
Vision Creation Newsun. Not really my kind of thing but I've enjoyed it.
Giant Steps. Loses a point because "Mr. P.C." is one of my least-favorite jazz standards, but "Giant Steps" and "Countdown" are both pretty cool and "Naima" is pretty.
The Stone Roses. "She Bangs The Drum" is great but I've never liked anything else I've heard by them.
Doggystyle. Has a couple iconic songs, but I suspect the whole thing would get repetitive for me.
Lift Yr Skinny Fists. There's probably some good stuff in here, but I mostly only like post-rock when it's scoring the Friday Night Lights TV show.
Deep Purple In Rock. I taped this from the library once but I'm pretty sure I never actually listened to it, and I don't regret that.
