Get psyched — the Source Festival is back! When the Source Theater went off the map for awhile, so did the annual event, but it’s returning this year. The event boasts interesting collaborations between seasoned artists and rookies, and creators in different mediums. It begins June 21.

What else is this month? For a little mystery to liven up your summer, try Agatha Christie’s classic, The Mousetrap. Olney is staging the work (June 11).

It’s also summer musical season. First, ABBA fans can flock to Mamma Mia at the National (June 24). The Kennedy Center has The Lion King (June 26) and summer’s the Season of Love when Wolf Trap hosts Rent (June 27).
