Following three weeks of successful performances, Martha’s Vineyard Playhouse presents the final presentation in its Spring Solo Shows this Friday and Saturday evening, May 25 and 26. “Truth Values: One Girl’s Romp Through M.I.T.’s Male Math Maze,” written and performed by Gioia Di Cari, will play for two nights at 7:30 pm. Di Cari creates “refreshing delights of humor, even compassion,” according to EDGE Media, while bringing to life more than 30 characters and presenting a conversation catalyst about gender equity and diversity issues, particularly around under-representation of women in STEM fields. Di Cari’s performance received a FringeNYC Overall Excellence Award for Best Solo Show. Tickets for both performances are $35, reserved seating. Tickets can be purchased in advance online, or by calling the box office at 508-696-6300, or on the night of the performance, subject to availability. For more information,visit mvplayhouse.org.
