NU-DISCO IN FORT WORTH: So much of marketing a band is putting a label on its sound. “Indie rock,” “alt country,” “emo” – these are all just ways of giving an unfamiliar audience a shorthand for what they’re about to hear. The trouble is, a lot of bands defy easy labeling. That was the case for Fort Worth trio Shuttle. So you have to love them for coming up with their own label: “nu-disco.” “Nü-disco is a white idea, a suburban, middle-class, spastic, nerdy thing that still has soul to it,” the band’s bassist, Matt Skates, tells Fort Worth Weekly. “I grew up in suburbia. I like cool beats, but I can’t dance.”

A MAGNIFICENT MACCA: If you were one of the unlucky souls traveling along I-30 last night, you probably found yourself wishing you had found a way around the double-bill of Paul McCartney at Cowboys Stadium and the Rangers playing next door. But if you were wading through the traffic to see McCartney, then it sounds like you had a good time. “McCartney projects an air of vitality, not finality; if this is Macca’s last jaunt around the U.S. (as has been rumored), he’s going out on a high,” Preston Jones writes in his Star-Telegram review. Mario Tarradell agrees on dallasnews.com, “Clearly, this man could play two more long shows of well-known hits without a bit or repetition.”

SPLIT DECISION: Mamma Mia! is taking up residence at the Music Hall at Fair Park, so if you saw the movie but never the stage show, there should be ample opportunity. The question is: do you want to? Theaterjones.com says yes. “It’s not high art, but it is one of those shows that helps make theater accessible to mainstream audiences with music that is familiar, nostalgic and fun,” Cathy O’Neal writes in her review. “It is OK for theater to just be fun.” Dallasnews.com says save your money. “If you’re an ABBA fan, you’d be better off spinning your home disco ball, glamming up in your bell-bottom PJs and cranking up ABBA Gold,” Joy Tipping writes in her review.
