Illinois Entertainer:

Power trio Pyrite's five-song sampler, Iron Soul Fight, equally straddles both avant/ jazzbo and nihilistic/agro/rock. Or as the band puts it, Gang Of Four crossed with The Jesus Lizard – to which one could also add a tempering of no wave sensibility. The dual vocals – one deadpan, the other more screaming – are an interesting turn, even if the lyrics aren't all that clear. But beyond the solid bass and drum playing, the way the guitar lines consistently veer from the "expected" ending pleases throughout. (www.myspace.com/pyrite312)

Hex Reviews:

This starts off with a real wiry guitar and drums thing, thick on the bass, almost as if it were an art rock band. Then it gets a little dirtier, recalling something sort of like Shellac. But then we get into some harmonized choruses, and get back into weirdness, like a more recent Dischord-type band... a little bit of older El Guapo, or Antelope. And yet there is also an older vibe happening as well, akin to Wire and Gang Of Four (though not nearly as funky). Overall it has a vibe that 25 years ago would be playing alongside Television and Talking Heads at CBGB's. Nowadays it's considered art-rock. (myspace.com/pyrite)

Punk Record Reviews (Sweden):

5 tracks from this new Chicago post-punk band.
Deep bass and screeching, shredding guitars in a clear production. The opening song Arrest That Cop is really cool. A bit like a fast CRUCIFUCKS or MINUTEMAN song.
Automatic Drip sounds like WIRE but with an american pop accent. In the opening of the final track Rocket To The Rock Bottom the vocals even remind me of good old OZZY.
Check it out if you like other stuff than punk rock too.

Though Iron Soul Fight may be considered a demo, Chicago trio Pyrite has the well defined sound of a much older band. Featuring ex-members of The Boyfriends and Peralta, Pyrite attack their tunes with off-kilter accuracy like The Minutemen and incorporate looming, less traditional arrangements like the ones found on Wire's Chairs Missing. The combination of tight instrumentalism and a desire to avoid post-punk clichés is as refreshing as a handful of ice cubes stuffed down your shorts. Brandon Bayles' thick bass tone provides melodic color for guitarist Mike Green to scrape away at with brusque, disjointed riffs. Iron quickly shifts from the pointed thrash of "Arrest That Cop" to the spacious opening of "Air Show," which roars to life during the punchy chorus. "Automatic Drip" is about as "normal" as Pyrite gets – a tight jam that makes Joe Jackson ache for his good ol' days. As the demo closes with the brilliant and unusually hook-filled "Rocket to Rock Bottom," it's easy to see that Chicago has another ace act on its hands that is not to be slept on.
