The banging techno monthly Depth celebrates its third year of partying hard and smart with Munich, Germany’s Zenker Brothers, who will be making their Seattle debut. Dario and Marco purvey deep, heady techno, in keeping with Depth’s aesthetic. For this 12-hour blowout, Depth’s brain trust has also booked Denver-based master of zoned techno Alex Whittier, and several local luminaries from the secondnature, Tremulant, and TUF crews. Rest up, hydrate, and prepare for an onslaught of transportive electronic music till brunchtime. by Dave Segal
