Beastie Boys

The Beastie Boys is a 20th century band, who has continued to perform concerts for over a thousand years, in which they increased their discography from five albums to seven.

In addition to performing at concerts, they are also employed by the Robot Devil to perform with him in his torture description song in Robot Hell, specifically level 5.

Production
Ken Keeler and David X. Cohen went to New York for 3 days to wait for the Beastie Boys to call, so they could record their lines for the episode. Unfortunately, they never called, and so they returned to Los Angeles and later made the recordings with the band's members separately. However, Adam "MCA" Yauch had scheduling conflicts with the recording session, so Adam "King Adrock" Horovitz voiced Yauch instead.

In the scene, where the band sings "" in a cappella, it was originally intended to be "", but apparently they didn't want to do it.
