Want to go hard at the library on a weekday morning? We’ve got you covered.

Denver Public Library is hosting Wheelchair Sports Camp, the hip-hop group led up by Kalyn Heffernan, on Tuesday, August 9. They’ll set it off at 9:15 a.m. outside the central library, 10 W. 14th Avenue Parkway.

Here’s a sample of Heffernan’s work, which sets her bars against a mix of jazzy instrumentals and experimental electronics.

The concert is part of the library’s sunrise series, which aims to bring a little joy to the library’s front steps, where homeless people often gather to wait for the doors to open.

“If we can just make a simple difference, I think it’s our duty to be a light to people who are in a dark place,” said Brandi Shigley, one of last year’s performers, in a Westword piece.
