Sigmoid Argonaut are five dudes from across the Sound who are cooking up some mean, proggy noise. When I saw their name surface recently on a reliable experimental music blog, I’ll admit to being a little bewildered. My naïve take on Poulsbo musicians has been that they are either indebted to Bremerton’s once-bright hardcore scene (Valley of the Dinosaurs, Kane Hodder) or they are, in fact, Dave Bazan.

Regardless, the tunes on Sigmoid Argonaut’s self-titled EP are pretty riff-tastic and fun. Seconds in, they’ll have you finger-drumming on the top of your desk. The band doesn’t stray too far from a driving, dopey vibe, but they have a real knack for the kinds of ebbs and builds that make post rock so irrepressibly bombastic. The guitars sear, the synths are molten and thickly-LFOed. However, Sigmoid Argonaut does seem to posses that dangerous aural samey-ness that can come with the unimaginative use of certain pedals (that is to say, the keenest of listeners might easily be able to attribute their sound to a specific combination of Guitar Center purchases). By comparison, an example of a band that uses their gear brilliantly would be non-peninsular face-melters Sleepy Eyes of Death. To be fair, occasionally, as on “Trapperin Keeper,” a really left-field noise will invite itself into Sigmoid Argonaut’s dirty-bong jams, adding a welcome dose of weirdness.

You can listen to two of Sigmoid Argonaut’s EP tracks streaming via myspace. Their next performance will be (unsurprisingly) a ferry ride away from Seattle proper, in Bremerton, at the Charleston on Feb. 2nd.
