Most Stax stuff is great. Jamerson cut a lot of his tracks done in LA with a B-15. Paper Tiger by Beck's a good one. Ted Nugent's early stuff was done on a B-18. The Stones cut a lot of stuff with a B-15. Peter Cetera used one with Chicago. Most tracks Klaus Voorman cut used one (Lennon's solo stuff, Carly Simon's "You're So Vain"). Ronnie Lane used one with Rod Stewart and the Faces. I could think of more once I wake up.
