Berlin producer/DJ Mark Ernestus made his exalted rep in the 1990s as co-architect of Basic Channel’s dub-techno hypno-scapes alongside fellow groove scientist Moritz Von Oswald. Ernestus later burnished his legend with space-dusted roots excursions accompanied by emotive reggae vocalists in Rhythm & Sound. Under myriad aliases, he and MVO honed a stripped-down, machinic species of club music that’s influenced thousands of cerebral 4/4 psychonauts. For this rare Seattle appearance, Ernestus is DJing and arming venues with a disclaimer that promises “dub and reggae, mostly instrumental, from deep roots to militant steppers, roughneck electronics to digi minimalism, heavyweight doom to hardcore uptempo. On occasion, he plays West African dance music.” So don’t expect Basic Channel’s greatest hits—and prepare to get BASSed. by Dave Segal
