Good reviews and nominations from the Outer Circle Awards (including Outstanding New Off Broadway Musical), Lucille Lortel Awards (including Outstanding Musical) and Drama League (for Distinguished Production of a Musical) helped prompt the extension.

The recently recorded PS Classics cast album will go on sale exclusively at the theatre and online at www.psclassics.com on May 20, two weeks ahead of the June 3 street date.

Direct from a smash world premiere by Chicago's Next Theatre Company last season (winning the Joseph Jefferson Award for Best New Musical), Adding Machine features a score by Joshua Schmidt and a libretto by Jason Loewith and Schmidt, inspired by Elmer Rice's 1923 play, The Adding Machine. Under the direction of David Cromer, Adding Machine stars Cyrilla Baer as Mrs. Zero, Joel Hatch as Mr. Zero and Amy Warren as Daisy (all reprising their acclaimed performances from the original production). The featured cast includes Joe Farrell as Shrdlu, Jeff Still as the Boss, Adinah Alexander as Mrs. Two, Niffer Clarke as Mrs. One, Roger E. DeWitt as Mr. Two and Daniel Marcus as Mr. One.

"Darkly comic and heartbreakingly beautiful, Adding Machine…tells the story of Mr. Zero, who after 25 years of service to his company is replaced by a mechanical adding machine," according to producers. "In a vengeful rage, he murders his boss. An eclectic score gives passionate and memorable voice to this stylish and stylized production, which follows Zero's journey to the afterlife in the Elysian Fields where he is met with one last chance for romance and redemption."

Adding Machine is produced Off-Broadway by Scott Morfee, Tom Wirtshafter and Margaret Cotter and features scenic design by Takeshi Kata, lighting design by Keith Parham, costume design by Kristine Knanishu, sound design by Tony Smolenski, projection design by Peter Flaherty, properties design by Michele Spadaro and musical direction by J. Oconer Navarro. For more information visit www.addingmachineamusical.com.
