Calgary folk-rock duo Tegan and Sara, U.S. indie band Yo La Tengo, Toronto collective Broken Social Scene and Antigonish, N.S. rockers The Trews are among the bands set to take the stage in Calgary this summer.

Organizers of the fledgling Sled Island Festival announced Thursday its full musical lineup. Tegan and Sara, Yo La Tengo and Broken Social Scene will be among 160 acts to perform at the second edition of the downtown Calgary festival.

A sneak peek of the bill organizers revealed in March included performers such as Mother Mother, the Wet Secrets, Of Montreal, Rza and Drive By Truckers.

The main Sled Island site will be an outdoor stage set up in the city's Millennium Park, with other concerts — as well as film screenings, comedy showcases and art exhibits — taking place at other venues around Calgary. The festival runs June 25-28.
