 "No Sleep till Brooklyn" was a popular concert favorite for the Beastie Boys and traditionally used as their closing song.Among other references to then-popular metal, the title is a play on the Motörhead album "No Sleep 'til Hammersmith".Kerry King, guitarist for Slayer, played the guitar riffs and solo; Slayer had released an album produced by Rick Rubin in 1986 ("Reign in Blood").
