The Beasties dropped this master jam in the summer of 1998, back when release dates really mattered, and for a week or two it was all you heard, anywhere you went. It's the last of their big Nineties statements, with Mike D summing it up in the electro-boogie hit "Intergalactic": "I am known to do the wop!" The Beasties stir-fry all kinds of beats in their wok, from old-school hip-hop and head-checking punk to bossa nova and reggae, as they speak out in favor of break dancers, ravers, the Knicks, Boggle and Buddhist introspection. Lost classic: "I Don't Know," a Brazilian-flavored guitar ballad where Adam Yauch ponders reality with Japanese rocker Miho Hatori.
