Eddie F & the Untouchables, "Let's Get It On" (1994)
This single from underrated Heavy D & the Boyz producer Eddie F's Let Get It On (The Album) is one of the few times 2Pac and the Notorious B.I.G. appeared in the studio together. The onetime friends traded bars alongside Grand Puba, Heavy D and Spunk Bigga over a bubbly sample of Barry White's "You're the One I Need." Biggie closes it out with a tongue-twisting verse: "B-I-G top notch with the glock, check your pockets and your sockets."
