Music Preview Jim Walker April 14 at Indy CD and Vinyl, 5 p.m. (free) April 14 at the Vogue with South and Something for Rockets, 8 p.m. ($12) Margot & the Nuclear So & So's, in the midst of touring behind its record, The Dust of Retreat, returns to Indianapolis Thursday for a show at the Vogue and an in-store performance at Indy CD and Vinyl. The band, which features eight players on a host of offbeat instruments, recently signed a deal with the national record label Artemis. Margot is making its way around the country in a converted short bus that once served as a mobile laboratory. The bus provided the biggest snag, so far, on the tour when it broke down in New Jersey. The band had to miss two dates in Canada while waiting for transmission repairs. "New Jersey was the worst possible place for that to happen," said guitarist Andy Fry, calling from a stop in Cleveland. Most everything else is going well. Fry said he and his band mates are enjoying the other groups they're touring with, South and Something for Rockets. They've also been pleased with the rooms where they're playing, mostly theaters. His favorite was the 930 Club in Washington, D.C. "It was a really nice place, the best sounding room we've played. Plus, there were teen-age girls screaming at us like we were the Beatles. Or maybe it was three of them who made a lot of noise." Fry is excited about playing at home - and getting a couple of days back in Indianapolis. "It's will be good to see everybody and take South, who is from the U.K., out and show them some of our watering holes," he said.
