Here’s a fun way to spend this Sunday, June 26: the Sunday Groove at The Tre3Hau5. The 14-hour event (yep, that’s 14 hours) runs from noon to 2 a.m. with three stages and 42 DJs spinning all types of music including techno, trance, breaks, drum & bass, bass music, 80s/90s/00s party jams, remixes & throwbacks. FREE hot dogs and hamburgers (veggie burgers and gluten-free buns, too) and fresh fruit and snacks galore will be dished out all day and night. The first 100 people through the door get a FREE water pistol to keep cool. Also on the schedule: artists painting live. According to organizer Ryan Dykstra, the venue will have plenty of misting machines to fill the entire front patio upstairs facing Lincoln. These machines drop the air temperature outside by up to 30 degrees. So…..feel free to wear your tank tops, bikini tops, swim trunks if you like. Entry is $10 at the door and includes all the food you can eat from the grill. Do note that this is strictly a 21+ event and held rain or shine. 776 Lincoln St., Denver.
