Take the aggressive in your face attitude of Primer 55, the dirt in your teeth down home grin and vibe of Clutch and combine it with the southern flair and riffery of Stuck Mojo and you'd have a pretty close comparison to Boiler. Big riffs, stomping grooves and a general unwashed feeling are what's contained on this EP's 6 tracks which comes complete with a solid cover of the Pantera classic "Mouth For War".
Vocally, the group draw comparisons to Clutch frontman Neil Fallon in his earlier days, barking out hoarse throaty verses like a demonic drill sergeant. Backed by a loosely assembled collection of large groove heavy guitar riffs, the high end is fairly straight forward and chooses to pounce on the listener rather than dazzle them with bone crunching riffs or technical proficiency. Meanwhile, the low-end chugs along underneath with a competent outlook and the drums are crisp and beat out their parts with a resilient snare and roomy tom hits full of reverb.
Overall the EP is a solid journey and the band have enough panache and flair of their own to leave a lasting impression. It's crunchy and militant, but rather than hitting like a baseball bat to the head, its more along the lines of being slapped across the face with an undercooked slab of steak. It's not so much that the music is a bit lacking, because its not, its just that the whole vibe is more akin to the laid back attitude of drunken dirt rock meets Pantera rather than pummeling metal. In fact, Boiler's music could probably best be summed up as the heavy metal version of the movie "Deliverance", except rather than ass fucking, there's ass beatings. As such, it'd be a great CD to play if you're sitting on the tailgate of a pickup with a cold beer in hand or something along those lines. But if you're looking for a full on emotional release or depth and longevity, you might want to pass the barn by and head for the city... yee-haw.
