Syrhea Conoway isn’t a DJ, and Contemporary Art Museum St. Louis isn’t a dance club. Yet Conoway — in the guise guide of her solo project, Syna So Pro — is CAM’s new DJ-in-residence. She’ll fill monthly, two-hour sets with instrumental pieces she’s writing in response to the art on display at the museum, beginning with Christine Corday’s cosmic-minded sculpture collection “Relative Points.”
