Playwright-composers Matt Gould and Griffin Matthews have paired up for a compelling performance piece that’s already won awards and earned accolades. ‘Witness Uganda’ made its world premiere at the American Repertory Theater earlier this year under the direction of Tony winner Diane Paulus. Now, Gould and Matthews bring the show to the intimate settings of the Sonoma Valley. As part of the summer-long Transcendence Theatre series, this one-of-a-kind concert experience combines Afro-pop music with personal stories and world-changing ideals. Witness Uganda plays under the stars on Tuesday Aug. 19, at the Atwood Ranch, 12099 Sonoma Hwy., Glen Ellen. 7:30pm. $35—$60. 877.424.1414.
