Boom Chicago

How to Explain It

"Short, fast scenes. Strong initiation: we know who you are and where you are in the first line. When you see the game of the scene, play it. When it is done, it is done. Edit yourself. No dragging, no explaining."

Boom Chicago teaches several foundational improv skills simultaneously: strong initiations, recognizing the game of the scene quickly, and self-editing.

Begin by having performers practice "one-line scenes" in which the entire comic premise must be established and resolved in a single exchange. This strips away the instinct to build slowly and forces performers to lead with their strongest idea.

Progress to two-line and three-line scenes, coaching performers to identify the exact moment a scene has peaked. Ask the group: where did the laugh happen? Everything after that moment is excess.

Coach the backline on aggressive editing. The most common failure in this format is scenes running too long because no one on the backline commits to the sweep. Assign a designated editor in early rehearsals to build the habit of cutting at the peak.

Another common pitfall is performers defaulting to the same type of scene repeatedly: all dialogue scenes, all physical bits, or all callbacks to earlier moments. Coach for range and variety across the set.

The format also builds ensemble awareness. Performers must track who has been on stage, who has not, and what energy the previous scene carried so that the next scene provides contrast rather than repetition.

The game requires a minimum of four performers to maintain the pace of rapid scene transitions. Six to eight performers is the ideal cast size, providing enough variety to sustain the format without repeating pairings.

Speed is the game's defining characteristic, but speed without clarity produces confusion rather than comedy. Each micro-scene must establish its premise within the first few lines. Performers who spend time building context or layering details lose the audience before reaching the payoff.

The edit is critical. Scenes that run past their comic peak deflate the energy of the entire set. Performers waiting on the backline must watch for the moment a scene hits its highest point and sweep immediately. Hesitating even a few seconds after the peak allows the energy to drop.

Variety in scene content prevents the format from becoming monotonous. Alternating between two-person dialogue scenes, physical bits, character pieces, and direct-address moments keeps the audience guessing about what comes next.

The backline must stay alert and ready. Dead time between scenes breaks the format's momentum. Performers should have initiations prepared and step out with confidence the instant the previous scene ends.

The game takes its name from the Boom Chicago theatre in Amsterdam, founded in 1993 by Andrew Moskos and Pep Rosenfeld. Both founders were Americans from Chicago who brought Chicago-style improvisation to the Netherlands. Boom Chicago performs in English and has become one of Europe's premier comedy institutions.

The theatre's performance style, described by Tom Salinsky and Deborah Frances-White in The Improv Handbook as "hugely successful and very slick," shaped the game's emphasis on speed, polish, and audience-pleasing economy. The Second City Chicago and Boom Chicago established an exchange program, facilitating cross-pollination between American and European improv traditions.

Boom Chicago's roster of alumni includes Seth Meyers, Jason Sudeikis, Amber Ruffin, Jordan Peele, and Kay Cannon, all of whom moved from the Amsterdam stage to major careers in American comedy and entertainment. The theatre's emphasis on high-energy, fast-paced performance influenced the development of this game format as a distillation of the Boom Chicago house style into a portable short-form structure.
