URO. It was constructed by Sal Clemente and Alan Ware. Initially, they were putting together a mode modernized version of “Jesus Christ Superstar.” Then, they ran into legal trouble from Andrew Lloyd Webber. Long story. The result was “A Night at the Rock Opera,” a live show that ncludes a partial staging of “Superstar” songs alongside their take on the Webber travails, “Will We Rock You?,” and rock-opera-ish tunes from Queen, David Bowie, the Who, the Beatles and others. They – and by they we mean a cast of a couple dozen - started doing this at the Regent Theatre in Arlington in 2006 and it is there they return for a three-date run that concludes Sunday June 1. You can be sure the URO will treat the material with both respect and a certain tongue-in-cheek flair. (They do not attempt to “act out” the songs; this is music, first and foremost, linked by era, genre or attitude.) What URO does stands in sharp contrast to post-rock,  minimalism, hip-hop, death metal, emo, and the new wave of the new wave. Which is to say, this is music that existed – gloriously, if sometimes cheesily – back before all of that. It’s up to bang its gong again. Will you, will you like it? Check out the URO website, www.anatro.com for a peak at what they do. Tickets: $35-$20. Show at 5:30.
