In an attempt to offer hope, light and beauty in a difficult time, Medford composer and conductor Oliver Caplan presents another of his weekly Wednesday night live-streamed solo performances featuring members of his contemporary chamber music group, Juventas New Music Ensemble. Performing this week will be french horn player Anne Howarth. She is a founding member and outreach director of the mixed-instrumentation chamber group Radius Ensemble and is a senior member of the wind quintet Vento Chiaro. She teaches horn and coaches chamber music at Tufts University and the Boston University Tanglewood Institute.

Visit the Juventas ensemble’s Facebook page promptly at 8 p.m. to enjoy the performance, which is free and open to all. The series continues every Wednesday night through May 27.
