Anything, and I mean ANYTHING, by James Jamerson, Donald "Duck" Dunn, Bootsie, or Carol Kaye. The fingers on all these people just drip with tone and funk. Hard for me to pick a fav among this pantheon of greats, but if I had to, it would be Jamerson, the iconic Motown sound with bass lines like "Bernadette" and "Reach Out" Awesome stuff
