System of a Down has been confirmed as the musical guest on "Saturday Night Live" on Saturday, May 7. This will be the band's first-ever appearance on the show, and they'll perform two songs - "B.Y.O.B." and "Chop Suey." Johnny Knoxville will be hosting, so be sure and tune into your local NBC station.

The second half of System of a Down's Mezmerize/Hypnotize will feature the band's first instrumental ... and make sure you call it that. When bist Shavo Odadjian referred to "Hezze" as a jam recently, singer/guitarist Daron Malakian quickly corrected him. "It's not a jam," he said. "It's a song, but it's a jam because it's without vocals, that's why I say that," Odadjian argued. "It's an instrumental," Malakian insisted. "You know how anal I am about that word. [I hate] when people call clical music 'songs.' They are not songs. You've got to sing for a song. Music is instrumentals. It's important to me. It's not a jam either, because jams are improvised."
