Saturday, Jan. 11, Pink Floyd tribute artist The Machine will bring a bit of "Dark Side of the Moon" to Rhythm & Brews, 221 Market St. The tribute collective is the brainchild of a group of New York-based fans of the British psychedelic rockers and, since its foundation in 1989, has performed 150-180 concerts a year. In 2011, the band performed a collaborative headlining show at Riverbend with the Chattanooga Symphony & Opera. Saturday's show starts at 10 p.m. Tickets are $20.
