Forty-five years after Pink Floyd's David Gilmour filmed Live at Pompeii in the city's Roman amphitheatre, he returned for two shows that were part of his year-long tour in support of his latest release, Rattle That Lock. The concert film David Gilmour: Live at Pompeii, which screens tonight at 7:30 at the Capitol Theatre, captures that concert, which includes Pink Floyd classics such as "One of These Days," the only song that was also performed at the band's 1971 show. Tickets to the screening are $15. (Niesel)
