There's a LOT of good mid- to late-60s Savoy stuff.
Other than the Shepp/Dixon records, there's some Dixon-produced sides that are brilliant, by Marc Levin (flute/cornet); Bob Pozar (drums); Ed Curran (alto/clarinet); and Marzette Watts (tenor). Love all of them (still need the Watts in the appropriate form). The Bill Barron dates, of which there are three, are all really nice too. Modern Windows and The Hot Line (w/ Booker Ervin too!) are serious - all the Barrons are on CD, or were recently.
Perry Robinson has a nice, mellow but kinda "off-kilter" (lame phrase, but fitting) side called Funk Dumpling, with Motian, Grimes and Kenny Barron. I like that one.
Joe Scianni (piano) and Dave Izenzon cut a duo called Man Running that's interesting, though the pressing is absolute shite - not uncommon with Savoys in my experience. In addition to the Valdo, Bley had some good Savoy material, though it's not up to his later greatness; still, Bley/Swallow/LaRoca isn't a bad start!

There are inaccuracies in some tracks, personnel and titles here and there, but it's helpful - especially to find some weird ones.
