It's a good time to be a Busta Rhymes fan. Earlier in the month, the 41-year-old rapper made waves by releasing "Thank You," an incendiary new track with frequent collaborator Q-Tip. He's built on the excitement by announcing a collaborative mixtape with Tip due out in December and by stopping by A Tribe Called Quest's reunion performance during the Yeezus tour stop in Brooklyn. He's always there to lend a helping hand.

With his E.L.E. 2 album scheduled to drop at some point next year, we figured it'd be as good a time as any to celebrate Busta's long history of stellar guest appearances. From his innovative early work in the Leaders Of The New School to his role as an elastic-voiced hip-hop veteran, Busta verses speak for themselves. So come rewind 20 of Busta's best guest verses.
