From the creators of Bonnaroo and Outside Lands comes the inaugural Grandoozy Festival, taking place from Sept. 14-16 in Denver’s Overland Park.

Headliners for the late-summer/early-fall fest include rap superstar Kendrick Lamar on Friday, British indie-rock collective Florence + The Machine on Saturday and soul legend Stevie Wonder on Sunday.

Acts like Sturgill Simpson, Phoenix, Young the Giant, St. Vincent, The War on Drugs, De La Soul, Mavis Staples and more are also featured on the festival’s first-ever lineup.

“Our interest in producing a landmark festival in Denver was born out of spending years getting to know the city and local community and diving head first into its flourishing cultural scene,” festival co-creator Jonathan Mayers said in an official statement. “Superfly’s expertise in producing large-scale immersive festivals, paired with Denver’s distinct and unique personality, is the perfect match for creating Grandoozy, a one-of-a-kind experience that we hope becomes a source of pride and celebration for this amazing city.”

General onsale for Grandoozy starts Friday, March 23 at 10 a.m. MT, but there is a special pre-sale for Capitol One Cardholders starting March 21 at 10 a.m. MT. For more information check out the Grandoozy website.
