Metallica will sit down for an interview and perform on Comedy Central's The Colbert Report on Tuesday (September 24th). The band is on the promotional trail for its new 3D movie, Metallica Through The Never, which opens this Friday (September 27th) on IMAX screens before expanding to more theaters on October 4th. The film stars Dane DeHaan as a member of Metallica's road crew who is sent on a mysterious mission while the band performs at a sold-out arena and events outside grow more bizarre. Metallica reportedly spent $20 million of its own money to make the movie. The soundtrack, which features a number of Metallica classics performed live in the movie, will be out on Tuesday. The two-disc CD will come out on Metallica's own label, Blackened Recordings, also in digital and vinyl formats.
