The Outside the Box festival is returning once again this summer for five days of free performances and events across the Boston Common neighborhood, kicking off July 13. The event’s full lineup features more than 100 acts and performers with Vertical Horizon, Daughtry and Smash Mouth headlining, but we’ve got our eyes on the off-hours. Here are some of our favoritecan’t miss picks.

Lea DeLaria, July 16 9-10 p.m.
The “Orange is the New Black” star brings her act to the Tremont Tent, the festival’s dedicated performance space for those whose performances are considered “outside the box.” DeLaria, known as “Big Boo” from your Netflix binges, will mix her musical and comedic talents and hopefully some David Bowie covers from her sixth studio album “House of David” for her live show.

Kaki King, July 17, 8-9 p.m.
Kaki King was the first woman to snag a spot on Rolling Stone’s “guitar god” list and was invited to share her unique melodic methods at the TEDWomen 2015 conference. At Out of the Box, she’ll take the stage of the Tremont Tent as the festival comes to a close Sunday night. Prepare to be awe-struck.

Blue Man Group Drum-Off, July 16, 1-2 p.m.
Five finalists — including two Berklee students and three locals — are competing for the opportunity to perform with the group and a prize package worth $6,000. Each participant has two minutes to prove themselves worthy in front of the Capital One Stage on Saturday afternoon. Winner will be declared by a panel of judges and crowd participating — so get loud.


The Wild Feathers, July 16, 5:30-6:30 p.m.
These Nashville guys know how to get a crowd moving. Having just released their sophomore album (“Lonely is a Lifetime”) in March, the roots rock band, takes over the Capital One Stage on Saturday. What makes these guys unique? The band is made up of almost all former lead singers of other groups, meaning harmonious charisma runs through their veins.

Luke Murphy, July 14, 2-3:30 p.m.
Irish choreographer and performance artist Luke Murphy will bring his show “On Triumph and Trauma” to the Tremont Tent on Thursday following stints at Solas Nua in D.C. and NYU’s Jack Crystal Theater. Murphy’s visceral production examines the cultural and political identity of Ireland, from perspectives, both scholarly and imaginary.
