The Glass Menagerie, Annapolis Shakespeare Company - April, 2018

" the most striking and memorable thing about it is the brilliant original score composed by Marc Irwin…

 "…the original score and composition by Marc Irwin is astounding and memorable.

 "Whether or not this approach to the piece is fully intentional, a vision fully actualized by Director Donald Hicken, is unclear, but whatever its intent— muting the performances in favor of such stirring and evocative music works to the overall nature of Tennessee Williams’ popular play. Irwin’s score is that of nostalgia, inviting you into a world that is vaguely familiar and yet uncertain. Using Irwin’s music to inform the scene above lighting… is a curious approach that Hicken chooses for the production, but not one without merit. These indescribably evocative sounds that Irwin has composed are the living memory and reality of the play as it unfolds."

"Hicken utilizes these design elements to augment the stirring sensations created by the musical compositions, making this an aural experience not to be missed.                                                 

Amanda M. Gunther, March 31, 2018 Theatre Bloom

"As Composer and Sound Designer, Marc Irwin brings touches of music to the production, adding to the atmosphere. Songs from the club across the street drift into the apartment, allowing Jim and Laura to dance. Music with a melancholy, mysterious feel lingers at the start and end of each act, just enough to highlight the emotional sense, without overpowering the scene."

Charles Green, March 17, 2018, DC Metro Theatre Arts

"Misery, magic and original music by composer Marc Irwin blend nicely together throughout the production,"

Jeanie Casison, March 28, 2018, MD Theatre Guide

Kiss Me Kate, Annapolis Shakespeare Company - May/June, 2018

 "Marc Irwin brings out the songs wonderfully as musical director. Leading the orchestra from behind a spiral staircase to the left of the stage, he lets the music perfectly blend with the actors’ singing, always coming in clear without overwhelming the vocals."
