Combining disparate items is a hit-or-miss prospect: Sometimes, it’s great (peanut butter, banana, and bacon sandwiches) and sometimes, it’s disastrous (the brief marriage of Salman Rushdie and Padma Lakshmi). Capital City Symphony fuses two conflicting musical genres that just might yield something beautiful: classical music and go-go. It’s called, simply, the Go-Go Symphony, a performance that marries the instrumentation of a full orchestra with the syncopated beats and live dancers of go-go. Conductor John Devlin will merge genres from his podium as he directs the world premiere of “The Green Line Symphony,” an original work by Capital City Symphony’s own Peter Van Siclen. The composition—inspired by stops on Metro’s Green Line—toes the lines between jazz, hip-hop, and orchestral music. The Gallery Place movement, for instance, contains bucket drumming and dance traditions from around the world to reflect Chinatown’s diverse cultural history and street performers. The U Street section, true to its current status as a nightlife hub, is all about hip-hop beats and busy melodies. The Capital City Symphony performs at 8 p.m. and 10 p.m. at Atlas Performing Arts Center, 1333 H St. NE. $30. (202) 399-7993. atlasarts.org.
