KOAN Sound at Red Rocks Amphitheatre

KOAN Sound is on the bill for Friday’s Cyclops Rocks VI show at Red Rocks Amphitheatre, with doors and showtime both listed at 6 p.m. on April 24, 2026. (redrocksonline.com) The official event page lists Subtronics as the headliner, with KOAN Sound, Effin, DENNETT, Rohaan and KLO supporting at the Morrison, Colorado venue. AXS also lists the same April 24 lineup and start time. (redrocksonline.com) (axs.com) This is the second night of a two-day Cyclops Rocks VI run at Red Rocks, with AXS showing separate shows on Thursday, April 23, 2026 and Friday, April 24, 2026, plus a two-day pass option. (axs.com 1) (axs.com 2) For KOAN Sound fans, the booking puts the British bass music act on one of the country’s highest-profile outdoor stages, inside a Red Rocks calendar that includes 168 listed events. Red Rocks says it hosts “some of the biggest names in music” during a concert season that runs from March through November. (axs.com) (redrocksonline.com) The venue itself is part of the draw. Red Rocks says the amphitheatre sits at 6,450 feet above sea level between two 300-foot monoliths, Ship Rock and Creation Rock, and is open to the elements. (redrocksonline.com) That setting changes how people plan for a show. Red Rocks tells concertgoers to expect uphill walks from parking lots, possible sun, wind, rain or snow, and to arrive early because nearly 10,000 people can be entering and finding seats at the same time. (redrocksonline.com) Tickets for Red Rocks shows run through AXS, and the venue says AXS Mobile Delivery is the only admission method at the amphitheatre. Red Rocks also says tickets in Rows 1 through 4 are non-transferable and must be used by the original purchaser, who may be asked for photo identification. (redrocksonline.com) Red Rocks traces the site’s concert history to a venue officially dedicated in 1941 after construction by the Civilian Conservation Corps, and it describes the amphitheatre as a naturally occurring acoustic space. Friday’s show adds another bass-heavy night to that long-running calendar. (redrocksonline.com)
