Join us for the fourth summer of Tunnelfest, a renegade folk festival held in pedestrian tunnels. Meet us at 7:00pm for three short sets by local musicians Wychwood, Oddeline, and Afraid of Jazz, followed by the August instalment of the monthly Arlington Hootenanny. Bring an instrument and/or simply your voice and join us in singing songs together (mistakes encouraged). Free, but we will collect cash donations for High Jinx, who help people experiencing homelessness in Centretown.
