Forward-looking Twin Cities theater companies have been rushing to present the work of playwright Lauren Yee, and no wonder: Her pieces blend personal stories with a historical sweep and a highly relatable enthusiasm for pop culture. Last winter the Guthrie gave an extravagant production to The Great Leap, and this season’s Mixed Blood production of The Song of Summer will be followed by Ten Thousand Things doing The Hatmaker’s Wife and a Jungle/Mu co-production ofCambodian Rock Band. The Song of Summer is a romcom that pairs a returning rock star with a hometown friend who might be something more. When the play premiered earlier this spring in Rhode Island, audiences swooned, comparing it to a Hallmark card—in a good way. The show’s sincere emotions coexist with a timely consideration of what artists and audiences do when an undeniable earworm has some problematic lyrics. “[It’s] simultaneously heartwarming and breathtaking,” promises Mixed Blood artistic director Jack Reuler.
