Hailing from Los Gatos, CA, Dredg began sharpening their aggro-metal sound in the early 1990s. Comprised of Gavin Hayes (vocals/guitar), Mark Engles (guitar), Drew Roulette (bass) and Dino Campanella (drums), the group was performing in area clubs before they'd even graduated from high school. Dredg self-released the Orph EP in 1997. The ambitious Leitmotif followed two years late, and it was reissued with the band's 2001 signing to Interscope. El Cielo, Dredg's proper Interscope debut, arrived in autumn 2002, and Deftones producer Terry Date was at the helm for their 2005 effort Catch Without Arms.
