Sludge

Summonus formed in mid 2007 in Sydney, Australia through like-minded musicians wanting to create punishing and brutal sounds involving huge groove based guitar riffs, hauling powerful drums and acidic, gravel-fuelled vocals. Each band member has had experience playing in numerous other bands in Sydney, Melbourne and Scotland over the years from a variety of styles including Grindcore, Hardcore, Punk and Rock.

The House of Capricorn are a dark rock band spawned from the swamps below One Tree Hill, Auckland, New Zealand. 2001 onwards..

There are 3 bands that share the name Mammoth and one band formerly known as Mammoth: (UK) 1. After the split of Gillan in 1982, the bearded John McCoy (bass guitar; 19 stone) recruited session musicians 'Tubby' Vinnie Reed (drums; 22 stone), 'Big' Mac Baker (guitars; 24 stone) and Nicky Moore (vocals; 20 stone and 5'6") for his solo project.
Initially christened 'Dinosaur', they changed their names after complaints from a similarly titled California blues outfit.

Boston's DOOMRIDERS are sonically antisocial and undeniably unforgettable as they come. DOOMRIDERS are comprised of a stellar lineup featuring Nate Newton (Converge, Old Man Gloom), along with longtime friends Jebb Riley (There Were Wires, Disappearer), Chris Pupecki (Cast Iron Hike), and JR Conners (Cave In). The demon child of their collective unhealthy obsession with Classic Rock, Hardcore, and Skateboarding, DOOMRIDERS are a rare beast in today's music world. Their soulful no frills approach conjures the spirits of Thin Lizzy, Entombed, and damn near every evil in between.
