‘Hovering always in the background with exactly the note of lament Williams called for, is the haunting music provided by John Gromada.” (Sweet Bird of Youth, Williamstown Theatre Festival) Louise Kennedy, Boston Globe 7/4/06
 
"John Gromada's lovely piano-based score is plaintive, understated and elegiac, conforming to the traditional reading of the play as a sort of tone poem." (Summer and Smoke, Roundabout)
Ben Brantley, New York Times  8/10/96
"Whenever the cast falls short, the event is swept up in John Gromada's brilliantly apt sound 
score, a Varesian rhapsody for jackhammers and turbines." (Machinal, NYSF) Michael Feingold, 
Village Voice 10/23/90
"Sollie's Cradle is a work of bold theater, luscious dance, and John Gromada's wonderfully
spooky hypnagogic music."  Eva Yaa Asantewaa, Village Voice 2/8/94
 
The score and the sound design by John Gromada are a series of epiphanies; he lets the ear
see, smell, and taste as well" (Mountain, Lucille Lortel) John Simon, New York Magazine,
4/16/90
 “The art is not only in the wonderfully graphic, pointed and suspenseful words, but also in the most resourceful acting, direction, design, music and fabulous sound effects. Devised by John Gromada, these sounds -- natural phenomena, lusty human and animalkind, wave-swept shore and bustling metropolis -- are almost worth the price of admission. Note as well Gromada’s music.” (Shipwrecked - Primary Stages) John Simon, Bloomberg News, February 12, 2009.
 
John Gromada's eerie mood music is particularly effective in underscoring the children's fear of and fascination with the mysterious Boo Radley. It gives full dimension to an unseen character whose presence is nonetheless essential in establishing the divide between the cruel social arbiters of the community and the gentle misfits who rise up against intolerance and right perilous wrongs”. To Kill a Mockingbird  March 2, 2009 Jan Nargi  Broadway World -
 
Their work is immeasurably enhanced by this season's most inventive and playful sound design, created by John Gromada, all of it using physical objects rather than electronics or recordings. (Shipwrecked)  Barbara & Scott Siegel, Theatermania February 9, 2009
