Calgary's Sled Island Festival, now in its sixth year, will take place from June 20-23 with Feist and the Hold Steady headlining the final two of the four nights. This year's festival, which will feature more than 200 acts and 100 people from the art, film and comedy worlds, is co-curated by Andrew W.K., best known for his 2001 hit, 'Party Hard.'

Unlike most festivals, where crowds gather in a single location and walk back and forth to different stages, Sled Island will take place in over 30 indoor and outdoor venues in Calgary. As their website explains, the goal is to "open up as much of the downtown core as possible and fill it with as many types of people as possible - using the appreciation of good, thoughtful, fun music, as the impetus to get together."

The schedule has yet to be determined, but festival organizers released the complete lineup. Other bands playing the festival include Thurston Moore, Stephen Malkmus and the Jicks, Archers of Loaf, garage rockers Reigning Sound and Shadowy Men on a Shadowy Planet, who are best known in America for the theme song to the 1990s sketch comedy show, 'The Kids in the Hall.' In addition to performing with the Hold Steady, Craig Finn will also perform a solo set.

Tickets are on sale now for single shows as well as the outdoor stage at Olympic Plaza. Discovery Passes, which offer access to all venues over the course of the festival, are $199. For $349, patrons can purchase the Discovery Plus pass, which give priority access and several other benefits, are also available.
