Indy Alt Folk. The Tin Constellations, who are all from the National Capital Region, are a quartet led by Brent Smith on lead vocals and rhythm guitar, Rob Snasdell-Taylor on bass, Andrew Robertson on exceptional fiddle and Christine Graves – their newest member – on percussion and harmony. Brent’s song subjects are far ranging, and this evening they included: Aldershot Station, what birds might be thinking, a woman who went over Niagara Falls, robots on a space station and more.
