Photographer Glen E. Friedman, widely known for his work chronicling the intersection between punk rock and hiphop in the 1980s, has posted some beautiful shots of MCA, Ad-Rock, and Mike D from that era: "why A you see H".
The first time I heard them, and Adam Yauch, was when a friend from middle school handed me a home-copied dupe of this cassette tape EP [YouTube, and you can still buy copies on Amazon]. I played it over and over until that little black ribbon wore right out. Some of you may not know that the Beasties were a hardcore band before they became a hiphop band. Now you do.
I've embedded some Beastie videos from that era below. Fuck you, cancer.
