Kasseem Mike Dean (born August 30, 1978), better known by his stage name Swizz Beatz, is an American recor producer and rapper. He is the founder of the Full Surface Records. His songs are usually very bouncy and energetic, though his early work was known to be quite minimalistic and arguably experimental—it reportedly takes him an average of only 10 to 15 minutes to complete a song. In most modern Swizz Beatz productions, (such as "Top Down") the quick uttered phrase "Swizzy" is heard at the beginning and is accompanied by guest vocals from Swizz himself, although often uncredited.
