Hmm...I took a look on good ol' Youtube at the artists mojogirl mentioned, and the only one that stuck out to me was Willie Dixon. What I'm looking for is mostly along the lines of this:
YouTube - Willie Dixon - Bassology
Looking back on it, my last post wasn't really clear at all, obviously. I'm looking more for jazz, rather than blues. I want to hear full orchestras, like something you would hear in a Broadway musical, or in a movie set anywhere from the Roaring 20's all the way to the 50's. Keep it instrumental, though, for both of my requests stated above.
Too bad I don't know of anyone my age that listens to jazz (I'm only 17.)
