Melvins and Mudhoney are two band with deep, deep histories. Both Melvins and Mudhoney come from Seattle and its surrounding areas. Both of them have been around since the ’80s. (Melvins got together in 1983; Mudhoney formed five years later.) Bassist Matt Lukin was a founding member of both bands, though he’s not in either one anymore. Both bands were pivotal players in what came to be known as the Seattle grunge universe, and both bands had brief major-label tenures, though neither had any real mainstream success. Both have continued to bang away as underground rock lifers and transcendent live acts. And now both of them have come together on a EP that — perversely enough — you cannot buy.

As Brooklyn Vegan points out, Melvins and Mudhoney recently joined forces on a new four-song EP called White Lazy Boy. The long-running noise-rock label Amphetamine Reptile Records released the EP as a CD-only affair — no vinyl, no digital — and it’s already sold out. This isn’t a split EP; it’s a full-on collaboration, a new ad-hoc band that consists of nothing but legends. White Lazy Boy features the two longtime members of Mudhoney, frontman Mark Arm and guitarist Steve Turner, teaming up with the two longtime members of Melvins, frontman King Buzzo and drummer Dale Crover. Steve McDonald, the Redd Kross and OFF! bassist who joined Melvins a few years ago, is also on board.

The EP features two new tracks, “Walking Crazy” and “Ten Minute Visitation,” and there are also a couple of covers: Black Flag’s elemental 1983 rage-out “My War” and Neil Young and Crazy Horse’s 1975 slop-rocker “Drive Back.” The EP apparently came out last week, and some of the people who bought it have been helpful enough to upload the tracks to YouTube. Listen below.

The White Lazy Boy EP is all sold out now, but maybe you’ll get another chance to buy it here.
