You don't have to understand the question, you just have to understand Aric!!!
No, the question is a simple one (well, as simple as things get with Aric when he posts loaded, or seemingly loaded) - what records might be out there that go into someplace different than the what "we" already "know". I know that Aric's hip to Ra & Tristano, so those two REALLY obvious choices aren't an option. He was talking post 50s, pre 70s jazz, but a "hard bop" record, which basically means "jazz". Well, ok, we've gone beyond those parameters, but so did the kind of musicinas he's looking for.
OK, that's not a simple answer, but if I get the gist of the question, it's "what else is there that relates".
Berg relates, Bartok DEFINITELY relates (Reiner's CONCERTO FOR ORCHESTRA, Dude, get it NOW), all this stuff relates.
