Radio plays take center stage in City Lights Theater Company's annual "Lights Up!" festival of new works. Usually an in-person event, "Lights Up!" is being presented as a podcast series for the second year, with the eight plays specifically written as dynamic radio plays. Starting April 6, new episodes will be released every Tuesday for four weeks on Filament, City Lights' podcast channel. Expect comedy, drama, murder, bar flirtations, and what happens when that car you just got into isn't actually an Uber. All Filament programs are free; listen at cltc.org/filament or on all major podcast hubs.
