Rhea MacCallum and Vincent Terrell Durham are accustomed to writing a play in four-and-a-half days. They learned to while part of PlayGround-LA, one of the Southland’s most dynamic playwriting incubators (and sister program to the Bay Area-based PlayGround-SF). The cornerstone of PlayGround-LA is its Monday Night PlayGround staged reading series, featuring original ten-minute plays by local writers, inspired by monthly prompts. The season culminates with a Best of PlayGround-LA gala, presenting the year’s outstanding plays.
