American grunge band Mudhoney formed in 1988, and have been going pretty strong ever since. Though not much has been heard from them lately, they have released some tour dates to showcase their new punk influenced material.
Having influenced some of the most notable artists in grunge, such as Kurt Kobain, these fellas are obviously something special.
They hate to jump on the band wagon, and are always finding new ways to break the mould, the rules, and generally whatever else is lying around. Their attitude driven guitar rock is as noisy as it is utterly superb.
