"For Whom The Bell Tolls" & "Master Of Puppets" - Metallica [Colbert Report Live Videos]

Metallica were on The Colbert Report last night, an occasion which marked their first television performance since a 1997 appearance on Saturday Night Live.

The band sat down with Stephen for a brief interview, in which the band discussed their upcoming 3D film Metallica: Through The Never (or, as Colbert called it, Under The Sometimes). He also asked about the band members' need for anger to play such thrashing music: "Can you keep your anger up, James? Do you need anger Viagra?" -- which, I submit, should be called "Viangra."

Watch the full interview and the web exclusive performance of "Master Of Puppets" below.
