If you're looking more towards Acid, I'd recommend:

1) Stuff by the group Incognito. Lots of brass and great vocals (Maysa Lea), IMHO.

2) This is hard to find but fantastic:
Home Cookin'

3) Greyboy Allstars

4) Nuyorican Soul

5) Giant Steps Vol 1

Amazon has most of these so you can get a listen.
