Crafting a new mold

Local Tampa six-piece, catalyst: bring a brand new set of elements into the world of metal, hardcore, punk, rock, ambient, experimental.. essentially turning each one upside down and shaking out the best contents contained within. Looking at the mess, as one might look at the world around them and wonder, 'how does it all go back together?', catalyst: aggregates a world's worth of ideas and inspirations, often as haunting and menacing as they are beautiful and complicated into a singular sound that defines them individually against the status quo in any of those genres. It's hard to make music sound original these days, even harder still to make original music that sounds good. catalyst: accomplishes both in this blistering 11-track journey that takes the listener on a locomotive ride to hell and back, demonstrating what the soundtrack to the apocalypse might possibly sound like. Strange radio broadcasts are heard in conjunction with cannon-like kick drums, crushing guitars and thundering bass lines, which seem to be a focal point of consideration - they are not merely playing these songs, they are broadcasting them to the world, urgently. Just as one might anticipate a real 'end of the world' scenario, it doesn't necessarily unfold in a roar of destruction at once, but rather ebbs and tides, and draws just a bit closer to finality each time it surges forward. The 13 minute plus long NS 404 saga will leave you frightened and cowering by the time it's finished, and only the oddly soothing album closer "Demodulate:" is enough to pull you back, even with its whistling, screeching radio noise and hidden messages that seem to speak in some kind of code, possibly stating that it's all over... and we lost.

Blown Away

I have been pretty active with in the music scene for a while, but when i popped in this album, I was completely blown away. From the opening track to the channel scan and different samples; this album really takes you to a different level. The shredding guitar licks, to the rocking bass beat, and temporal blast beats and melodic sounds of the drums really make this a good addition to any fan of metal/hard rock/punk/ rock and roll etc. Killer breakdowns melded together in perfect symmetry with thought provoking samples about modern technology and how that vehicle can shape and shift our very souls really peaked my interest. Anyone who purchases this album will no doubt want more of this band. One of the hottest new bands out there, check them out of reverb nation as well.
