Robyn + Royksopp, Arcade Fire And More Must-see August Shows

It wasn’t long ago that we’d be complaining about the August doldrums, the period in which pretty much nothing happened in Washington, aside from a lot of sweating. But this month is filled with so many excellent concerts that we can’t mention them all here. Arcade Fire is bringing its disco road show to Verizon Center; dance queen Robyn’s unusual collaboration is landing at Wolf Trap; and hip-hop and EDM festival Trillectro is setting up in a new venue with such acts as Big Sean and Migos.
