Meltdown from Pittsburgh, PA is a radical mix of 85-89 era Megadeth and Slayer of the Reign in Blood period. The band relocated from their native Pittsburgh, Pennsylvania to Los Angeles, California in the fall of 2007. The band changed its name to Mantic Ritual in September 2008 to avoid confusion with other bands called Meltdown. They are re-recording their debut album for release on Nuclear Blast early in 2009 under the new moniker, however in late 2008 they moved back to their hometown of Pittsburgh.
