Progressive metal

There's more than one artist under this name:
1. Thorns (formed as Stigma Diabolicum, but changed name to Thorns after two years) is a Norwegian black metal band, masterminded by Blackthorn (Snorre W. Ruch - also in Mayhem and Satyricon). They made two highly influential demos in the early 90's, Grymyrk and Trøndertun, but have only released one full-length album, since the band was founded, in 1989.

In early 2008, a musical experiment was put in motion between friends and acquaintances. The idea was to put together four musicians from diverse musical backgrounds and see what could happen. Within a few months, Jurojin was born. Featuring a rock singer, a classical Indian tabla player, a jazz bassist, and a metal guitar player, this unlikely combination has been gathering attention and critical acclaim since their live debut in June of 2008 at London’s Borderline club.

Ed Zealous, the most electrifying band to hail from the burgeoning Belfast scene, were crafted from ice and flames and are prepared to chill the bones and fire up the senses with their precision rush of melody and guitars. As the Arcade Fire hit the covers of the London press, fledgling Belfast band Ed Zealous were left to combat an altogether less savoury arcade fire of their own. Discovered first by the legendary Ulster punk impresario Terry Hooley (lest we forget, the man who found us the Undertones), Terry had opened his Good Vibrations record shop to them to rehearse in.

Collision Process are a progressive metal band based in the UK's West Midlands. The band first came together instrumentally in early 2009 to write the music for their first self-titled EP, but it was the addition of lead vocalist Adam Cooper in early 2010 that completed the missing piece of the puzzle, and allowed for the vocal interplay between himself, singer/guitarist Jon Walters and bassist/backing vocalist Dan Willett that now plays a huge role in defining their sound, with abrasive screams weaving in and out between soaring harmonies and melodic call-and-response dynamics.
