The Lineup!

Summer Fling is a Baltimore-based indie ensemble. They perform the Pretty Flower improv form originating from a source monoscene. Our shows are full of fun, committed, and anarchic energy.

Sandcats performs a Pretty Spokane where they spin a narrative filled with flashbacks, flashforwards and what-ifs!

Babeprov is an all female group that takes the stage with a flirty deconstruction. They always serve a flawless show for all you trauma soaked babies looking for a little drama to get some joy in this life. They’ve brought their own brand of glamour to the stage and screen since 2021, performing together in Baltimore & NYC!

What is an improv show, exactly?

Improv is live theater created spontaneously by the performers with the inspiration of the audience. Unless noted otherwise, it’s a comedy show, made even more exciting, intriguing, and hilarious by the fact that none of it is pre-scripted! At an improv show you’ll see a wide range of creative and fascinating humans perform a highwire act by making comedy out of thin air! It can take many forms, including short competitive games, slice of life scenes, and full length sitcom or movie style performances!

A Highwire Improv show is truly a once in a lifetime performance, never done before and never to be done again!
