Daniel Osterhoff’s contemporary bass music night Grimey may have slowed down a bit over the last year (he had a kid, moved to Copenhagen, and recently moved back), but it is returning in a big, big way on Friday, June 5, 2015 at Midtown BarFly. To celebrate Grimey’s fifth anniversary, Osterhoff (best known as DJ Whores ‘round these parts) has lined up quite the epic party that will feature multiple rooms of music, 15 performers, crazy 3D mapped visuals with huge lighting and sound rigs to bring that low, low bass Grimey is known for. Performing in the main room will be Tiger Fresh from Portland’s We Got This crew, Boggan from Reno’s Future Strange crew and Mr. Kitt from San Francisco’s Ritual crew. In the kitchen spinning tunes will be DLRN’s Jon Reyes, and the front room will see the Requiem crew and friends bring the ruckus. Whores also alluded to a couple surprise guests that haven’t quite been locked in yet, but assured us that, “The secret guests will be the cherry on the cake.” Grimey is 18-and-over, and it runs from 9 p.m. to 3 a.m. Cover is $7 in advance or $10 at the door.
