2005 release of the New Orleans metal band Crowbar was originally comprised of vocalist/guitarist Kirk Windstein, guitarist Matt Thomas, bassist Todd Strange, and drummer Craig Numenmacher. Once known as the Slugs, the band's slow, grinding, heavy sound has alternately been tagged sludge metal and sludgecore, and has drawn comparisons both vocally and musically to Pantera, the Melvins, and Tad.
