The brains and brawn behind The Cataracs, Cyrano and Campa, are barely legal. No joke. They’re 18. Go find their album Techno-Hop. Lurk on www.myspace.com/cataracs. Maybe if you stalk them long enough, you’ll get to check out “I’m a Star,” “Gumdrops,” or another exclusive joint before they pop up on what’s sure to be a huge major-label debut.”
