MetalSucks is double-dipping this year at the annual showdown/brodown/hoedown in Austin, TX by bringing you TWO awesome metal shows. You already know about the amazing Full Metal Texas lineup during the day on Thursday, March 18th — featuring Darkest Hour, Howl, Fair to Midland, Iron Age, Karnivool, Iwrestledabearonce and more — and today we’re pleased to announce that we’re sponsoring the showcase for one of our favorite metal labels, Prosthetic Records. The lineup, starting at 7pm on the festival’s inaugural Wednesday night, features the future of Prosthetic’s roster: Scale the Summit, Landmine Marathon, Withered, Book of Black Earth and The Funeral Pyre. We haven’t heard of Clinging to the Trees of a Forest Fire or Lions of Tsavo before, but if Prosthetic gives them their stamp of approval they seriously must be excellent… and aren’t festivals like this supposed to be about discovering new music anyway?

But wait — there’s more! The Prosthetic showcase is taking place at the same venue as the Action PR showcase at the very same time, meaning once you’re in you’ll be able to freely roam between both stages, one inside and one outside. And check out THIS fucking lineup: High on Fire, Priestess, Bison B.C., The Gates of Slumber, Zoroaster and Namm. Holy fucktickles, are you kidding me? That’s 13 fucking awesome metal all for just $10 (free if you have a wristband) in one metal-filled evening. FUCK YES.

Coming soon: a MetalSucks-approved calendar of all the metal goings-on at SXSW 2010.
