Licensed to Ill is the debut studio album by the American hip hop group Beastie Boys. It was released on November 15, 1986 by Def Jam and Columbia Records. It was the first rap LP to top the Billboard album chart. It is also one of Columbia Records' fastest-selling debut records to date and eventually sold over ten million copies in the United States. Kerry King of Slayer made an appearance on the album playing lead guitar on "No Sleep Till Brooklyn" and appeared in the music video which is a parody of glam metal. The name of the song itself is a spoof on Motörhead's No Sleep 'til Hammersmith album. King's appearance on the track came about because Rick Rubin was producing both bands simultaneously (Slayer's Reign in Blood was originally released a month earlier on Def Jam).
