Do you sample vinyl or what?? I have some vinyls I sample from and i've picked up some classical records with some dope loops on it. Also if you have a local music store, most music stores have a "used" section. Just go through the used section of the cd's (classical or jazz mainly). They'll have a station setup somewhere so you can listen to them first. Mingus is dope though, I have a few of his albums.
