[Director Ciarán] O'Reilly has also overseen a gloriously dilapidated production design. Charlie Corcoran's set is a thing of crumbling plaster, dirt, and mold, with two tiny windows offering a peek at the nothingness outside. Orla Long's filthy-looking costumes are masterful studies in distressing fabrics for the stage. Sound designer M. Florian Staab's original music bookends the action on a sumptuously orchestral note.

"In its new production, Irish Repertory Theatre has gotten the bleak part down pat with Charlie Corcoran's set, a ramshackle "living" room that appears to be coming down around itself, with tattered curtains hanging in bay windows and bricks strewn about the floor, and Orla Long's costumes look equally threadbare and unkempt. Sound designer M. Florian Staab quietly fills the air with his subtly menacing music.

- Pete Hempstead for Theater Mania - Endgame

"The 7th Voyage" looks and sounds terrific. [...] The staticky video design by Jesse Garrison and the spacey music by M. Florian Staab smartly update the ominous vibe of 1950s sci-fi.

Even though only one [actor] can be shown on screen at any given moment, Mr. O'Reilly has staged their individual performances in such a way as to subtly suggest direct physical interaction, and M. Florian Staab's dark-and-stormy-night sound design heightens the verisimilitude still further. [...] The Irish Rep is now way out in front of every other company in America when it comes to marrying technical innovation with artistic quality.

For fans of Coward and his oeuvre, Love, Noël offers an intimate and authentic view of his charming and creative persona and a revue of 20 of his amusing and moving songs [...], in solos and duets by two of today’s most established cabaret artists (with a clear sound design by M. Florian Staab).

- Deb Miller for DC Metro Theater Arts - Love, Noël (Online)

[...] M. Florian Staab's 360-degree sound design suggests action in locations just offstage and behind the audience. The intimate house of the Irish Rep feels very much a part of the action.

A subtle soundscape by M. Florian Staab provides a hushed background of angry crowds, storm-tossed waves, and sacral music suited to the episodes imparted by Jennings [...].

- Deb Miller for DC Metro Theater Arts - The Gospel of John

[...] the sound design by M. Florian Staab unobtrusively introduces restless mobs and natural resonances. The production components in no way distract from Jennings' masterful storytelling.

- James Wilson for Talkin' Broadway - The Gospel of John

The sound design by M. Florian Staab provides the chilling underscore that facilitates the hair on your arms rising and a cold chill to run up your spine.

Lighting designer Bailey L. Rosa and sound designer M. Florian Staab have created some dramatic visual and aural effects as well as some subtle ones. (Staab also provides original music.)

- Mark Dundas Wood for TheaterScene.net - The Hope Hypothesis

M. Florian Staab's sound design - Dogs, birds, cars, celebrations - [is] completely clear, and I'm not even sure whether the offstage revelries in the second act are live or pretaped.

Confined to the side show, a look of hopelessness seizes control of his face as the crowds pass by on their way to more enticing attractions; at night, he cowers in his cage, surrounded by hostile animal noises. (These effects, and many more, including the sounds of train engines, a ticking clock, and various musical selections, are provided by the excellent sound designer, M. Florian Staab.)
