This Slayer CD, "Ubernoise," was released in 1998 as promotional material to supplement the album "Diabolus in Musica." Ubernoise contains interview segments with all 4 members of Slayer (Paul Bostaph on drums), live recordings of some of their classic songs, and studio recordings of selected songs from Diabolus in Musica. Additionally, this disc contains live concert footage and music videos accessible through a computer. HOWEVER, most operating systems have now surpassed the compatibility limits of this disc so you MAY NOT be able to access the videos. This CD is NOT a bootleg. I received it directly from Slayer's record label, The American Recording Company (American Recordings, as most people know it). The record label representative mailed it to me at the CD store that I managed to assist in promoting Diabolus in Musica.
