Swizz Beatz (born Kasseem Dean on August 30, 1978) is a New York-based American hip hop record producer/rapper of African American, Jamaican & Puerto Rican descent, and founder of the music label 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 took him an average of only 10 to 15 minutes to complete a song. In most modern Swizz Beatz productions, the quick phrase 'Swizzy' is uttered at the beginning and is accompanied by guest vocals from Swizz himself, although often uncredited. You would usually hear Swizz Beatz doing his trademark sounds/noises like the air-raid siren, gunshots, whistles, breathing noises, ghoulish sounds & the sound of a man saying "What!"/crowd cheer, or bells. Swizz Beatz also started a trend where he uses some of these sounds in more than one song. Such as the Touch It Remix by Busta Rhymes you hear the "what!"/crowd cheer, and you can also hear it in Ring the alarm By Beyonce. Other producers have started doing the same since. Producers such as Cool and Dre and E.T.C
