Signature Song: Large Professor "Ijuswannachill" (1996)

Although he's widely credited as a dope producer behind the boards, Large Professor is barely acknowledged for his skills behind the mic. But Xtra P's pen game is unquestionable for his work on Main Source's Breaking Atomsalone. If you don't believe us, just peep records like "Just A Friendly Game of Baseball," which combines a baseball theme with a not-so-subtle tale of police brutality that's as damning as it is inventive.

His legacy may have been tarnished by his tendency to disappear for long stretches. Shortly after Breaking Atoms dropped, Main Source broke up and P went solo. And although he did help mentor Nas in the early part of his career and went on to produce for everyone from Rakim to A Tribe Called Quest, P didn't put out too much solo material. His first solo album, the underappreciated 1st Class, didn't even drop until 2002. But hey, at least the album had awesome cuts like "Stay Chisel" on it.
