pat metheny group is some really good modern jazz - the album imaginary day is probably the jazz album i've listened to the most. the first circle is a bop, but the album itself starts with a song that is intentionally supposed to sound terrible.

bela fleck and the flecktones is like a combination of jazz and bluegrass, and they have a christmas album that features like throatsinging. definitely on the weirder end.

maybe not what you're looking for, but louis cole makes some really good funk. his first two albums have a bit of that lo-fi sound (mostly due to what he had to use to record), so i enjoy listening to them while i work on stuff. plus, if you enjoy his creative style, you can check out knower for electronic stuff or clown core for just weird shit
