Every now and then, a combination will go beyond "appropriate" or "good" and result in something that forever alters the universe. Just imagine a world without chocolate and peanut butter, Doc Martens and a leather jacket, Beavis and Butthead, and of course, Mudhoney and Sub Pop. April 2013 marks the 25th anniversary of both Mudhoney and Sub Pop Records, and there could be no better band to represent the label, past, present and future. Nirvana, Saint Etienne and Fleet Foxes are swell, but no other group has consistently kicked as much ass as Mudhoney, nor has anyone come close. Through two and a half decades, sarcastic grins remain implanted on their grizzled faces, even as empty bottles and the sneakers of a stage diver fly inches from their heads.
