Superheaven spent the past few years honing their grunge buzzing, and desperate sad sound across four EP's, showcasing and perfecting a talent for writing both jarringly heavy and delicately emotional songs.

With high-anticipation, the Pennsylvania four-piece deliver JAR, their debut full-length.

Engineer & producer Will Yip's massive production knocks you on your ass from the very first drum hit and snarling guitar riff.

The stadium-sound drums, plus pulsing bass and walls of buzzsaw guitars are all mixed with the size and clarity of major label grunge breakthrough records like Nirvana's Nevermind and Smashing Pumpkins' Siamese Dream.

Superheaven have delivered a towering rock record and an early contender for album of the year.
