The Solid Sound Collective, a music project of the St. Louis nonprofit Action Art Collaborative, celebrates the long and living legacy of community activism. Three of its producers and musicians – Colin McLaughlin, Ryan Marquez, and Alicia Revé – talk about original songs commissioned for the project and the role of interviews in creating music that addresses social and economic inequities. The collective premieres its music at an event on June 2 at Work & Leisure in Midtown St. Louis.
