The earnest and angsty Ethan Mark Nestor-Darling, better known online to his 2 million YouTube subscribers as CrankGameplays, presents ‘I Have To Do This Show’, a unique experience interlaced with comedy, theater, and a realistic—if possibly warped—viewpoint of the internet, from an online ‘influencer’. Part talk, part demo, the show at the Fitzgerald Theater is a rare glimpse of the massive online world of streaming an American video game commentator, vlogger, and one of the former video editors for Markiplier (who himself has 32 million subs) who has helped drive the medium. TUES, 8 PM. $37.50. All ages.
