For more than two hours at every performance of Just In Time at Broadway’s Circle in the Square theatre, Jonathan Groff inhabits the persona of famed singer Bobby Darin, to tell his story and celebrate his music. A talented cast and band also contribute to this visceral production. Sound designer Peter Hylenski was tasked with the challenge of making it all work as Groff makes his way past the audience to perform on the A and B stages. From “Theatre Sound” by Bryan Reesman, FOH, Sept. 2025.
