Chaos Theory presents a triple feature at The Black Heart, with both underground postmetal behemoths Tacoma Narrows Bridge Disaster and devastating prog band Opensight launching their albums, hoisted up on the pillar of rock that is the mighty Sumer. ﾗﾗﾗﾗﾗ Tacoma Narrows Bridge Disaster? (album launch) A brilliant atmospheric postmetal band whoﾒve risen early in the UKﾒs underground scene. Now back with the original lineup that won them their international audience, they launch their third album, three years after releasing the hugely acclaimed ﾑExegesisﾒ. Their audiences span the edges of metal, prog and postrock, which has led to them performing at this yearﾒs ArcTanGent Festival, as well as sharing the stage with bands as prolific and diverse as Pelican, Bo Ningen, Latitudes, Her Name Is Calla, Trojan Horse, Bast, Blueneck, Theory Of Machines, Alright The Captain, Lost In The Riots, Flies Are Spies From Hell, Eschar, Torpor and obe. ﾓﾅthe group have pulled off the remarkable feat of creating something steeped in influence, yet devoid of pastiche.ﾔ ﾖ Metal Hammer? ﾓTNBD have raised the bar for bands with a DIY ethic.ﾔ ﾖ Prog? ﾗﾗﾗﾗﾗﾗ OPENSIGHT? (EP launch) An ambitious prog metal band, originally from Columbia. Guitarist and founding member Ivan David relocated to London some years back, reformed the band and played a very early Facemelter exactly three years ago. Since then they have gone on to become a favourite at Bloodstockﾒs Metal2TheMasses, performing alongside Seethe, From The Ashes and Darkeye. With a sound that fuses metal with the vintage, grainy feel of 70s prog, Opensightﾒs launch of their new EP ﾑUlterior Motivesﾒ will appeal to fans of all genres. ﾓﾅa genuinely unique, powerful, rock band.ﾔ ﾖ SonicAbuse? ﾗﾗﾗﾗﾗﾗ Sumer? A selfstyled postprog band that has risen with seemingly unstoppable force, and with every reason, as anyone who attended the packed launch of their album ﾑThe Animal You Areﾒ last September will remember. The riffs remain interesting while maintaining soaring vocal melodies and catchy hooks. The wide span of influences in this band has allowed for them to perform with bands like Amplifier, Mordecai, Mask Of Judas and The Fierce And The Dead and at this yearﾒs DesertFest. ﾓﾅa sonic structure of melodic distortionﾔ ﾖ Prog ﾓﾅa force to be reckoned with.ﾔ ﾖ The Monolith?
