If you haven’t heard of the Cool Kids, maybe you’ve seen them recently on your new plasma TV that you got on sale over the holidays. They were featured recently on a Rhapsody commercial, and the Cool Kids are most definitely on the come- up. Known for their skater/BMX-ridin’ style, the “retro-rap” duo has a keen sense of style that I can predict will soon be duplicated by many 17-22 year old guys all over the US. Hear & see the Cool Kids in action for yourself tonight, Jan. 24th at Studio B in Williamsburg, Brooklyn. 259 Banker Street. 718.389.1880. $10. clubstudiob.com
