Here’s the Beastie Boys performing on public access television, 1984. Adam Yauch is playing bass in this clip. He’s about 19-20 years old. Kate Schellenbach played drums with the Beastie Boys between 1979 and 1984. She later joined Luscious Jackson.
Finally, here’s “Cookie Puss,” the group’s first hip-hop recording (some NSFW lyrics). There’s an interview with the young group after the break.
