With incommensurable delay here we're reviewing this "jazz"(?)-core clash of titans counterpoising Zu (with Xabier Iriondo) and Iceburn. The mighty Zu with the help of mister Iriondo (from Uncode Duello/A Short Apnea’s fame) floats in a new (at least for them) electro-acoustical territory, but without losing their typical jazz-core obsessivity and their hard pounding "bass and drum" repetitivity. Due to the improvisational/experimental essence of the session and probably cause of the heavy hand of Iriondo behind the mixer, this side could be described well speaking about physical post-core music with a Brotzmanesque saxophonist melt in an intentionally chaotic, heavy, electro-acoustical pool. The real surprise has come when I started listening to the Iceburn side, but before that, let's speak about these trio from Salt Lake. Hailing from the capital of Mormons, Iceburn has left from evolved, emotionally charged, metal-core growing into something gradually more progressive, jazzy and probably they've reached the top in "Poetry of fire". Later they changed their moniker and augmented their line up becoming The Iceburn Collective and this final release is played in trio with Gentry e Chad from the historical line up. Well, they've been one of the most interesting jazz/progressive-core band of the nineties (and "post core" would be a limiting definition for such a band) and here you can enjoy one of their many evolutions. These four songs presents an unheard sludgy post-Krimson obsessive incarnation of Iceburn. Less free jazzy than the last period, heavy as hell, psychologically devastating, this could be the declaration of love from this glorious band to some of their "hard playing" inspirators and let's include in the list people like: Black Sabbath, Melvins, Rorschach, Amphetamine Reptile, Dazzling Killmen and a good part of the Skin Graft catalogue, Ornette Coleman, John Zorn's Naked City and Painkillers and god knows who else. About twelve minutes to lose yourself in complaint for their never so missed departure even if they’ve generated and reinforced bands like Colossamite and Gorge Trio.
