Boiler Room Theatre, the area’s foremost purveyor of musicals, launches a three-night festival in which musical works that are still in the developmental stage are presented. First-round winners — chosen 60 percent by a panel of judges, 40 percent by the audience — move on to an opportunity for a staged reading at BRT, with the eventual grand-prize winner receiving a full production in 2013. Show authors are allotted 30 minutes to showcase their theme, story, dialogue and song samples, and there are three submissions per night. BRT artistic director Jamey Green and playwright Jim Reyland head up the judge contingent, which also includes local writers, producers, directors and critics, including Ted Swindley, Barry Scott, Maryanna Clarke, Nate Eppler, Amy Stumpfl (the Tennessean), Evans Donnell (ArtNowNashville) and Jeffrey Ellis (BroadwayWorld.com Nashville). According to Green, the contending scripts are an eclectic mix, ranging from rock to Gilbert and Sullivan. What has not yet been determined, however, is which judge will assume the Simon Cowell role.
