Osheaga

The Montreal festival's roster also boasts M83, Haim, the Arcs, Grimes, the Last Shadow Puppets, Wolf Parade and more.

It's not for sure yet, but it definitely looks like Radiohead will be headlining at least three major North American festivals this summer.

Rivers Cuomo brought out his 12-year-old daughter and three-year-old son to jam with him and the band during their Osheaga set this past weekend.

The lineup has been announced for Osheaga 2013, which takes place from Aug. 2-4 at the scenic Parc Jean-Drapeau in Montreal, Canada. The three-day festival boasts performances by Mumford and Sons, Phoenix and the Cure, plus dozens more.
