DJ Le Spam & Spam Allstars blend improvisational electronic elements and turntables with latin, funk, hip hop and dub to create what they call an electronic descarga. It’s not a known genre. It’s hard to describe. It attracts many types of people. But as they look out and see people dancing salsa, next to break-dancers, and festival-goers driving for hours to catch a show — they know something very special is going on.
