I'm definitely a Lacy fan, but of the three you mention, I only have Clangs. It's different: almost "classical" in its concentration on composition and on the types of compositions, and there is a fair amount of singing (though as Penguin pointed out, the voices are used almost instrumentally). If you're totally averse to Irene Aebi, you might want to stay away (but it sounds like that's not a problem for you). That said, I like the record. THAT said, I don't listen to it very often. (Though right now I find myself wanting to! I'll have to put it on when I get a chance.)
Blinks is very good, but similar (many of the same compositions), and even better, IMO, is Cliches, which I think should still be available from hatology. Lacy's great sextet with George Lewis sitting in. Great record. Morning Joy is also a must (it's the one that made me a fan in the first place), as is School Days which I recently picked up--very exciting record.
