For those not familiar with the genre Sludge Metal, meet Big Business. Hailing from Seattle and signed to Gold Metal Records, they traffic in crunchy, chugging jams with wonky, drop-tuned strings. Reminiscent of instrumental metal band Pelican, Big Business features echoing haunting vocals courtesy of Jarred Warren of the band Karp. Imagine the Melvins on codeine.
