Renowned Japanese innovators Boris and Merzbow have teamed up with Relapse for their new collaboration, Gensho, one of the artists' most daring works to date. Named after the Japanese word for "phenomenon," Gensho is a unique release featuring over 150 minutes of new music spread across two CDs and four LPs. The Boris songs are completely new, percussion-less reinventions of classic tracks from the band's storied catalog, while Merzbow’s songs are entirely new compositions. The two sets are intended to be played at the same time at varying volumes so that the listener can experience their own "gensho/phenomenon" every time.
