Despite what the company he sometimes keeps might suggest, Mattin is one of the biggest things going in punk. He is, when he wants to be, loud, brutal, lo-fi and strident. His songbook series is some of his most overtly rock stuff, improvised songs (verse and chorus) recorded into the internal mike on a laptop. And true to punk form, Volume 4 (two of the previous three are available for free download on his website, http://mattin.org) rushes by, six songs in 22 minutes. Recorded live in Tokyo in 2006 with four other musicians (two of them in the club's toilet), it's loose and ugly. The band (Taku Unami on bass and piano, Anthony Guerra on guitar, Jean-Luc Guionnet on sax and Tomoya Izumi providing additional shouting) includes some other typically quiet musicians, and they retain a sense of sparseness despite the overdrive. The improvised song forms, played without drums, make the album sound something like a Suicide quintet. It's cool, it's raw - your parents wouldn't like it, and your kids probably won't either.
