Performer/creators Trey Lyford and Geoff Sobelle burnish classic vaudeville schtick (pratfalls, spit-takes, sleight-of-hand, bad ventriloquism) with a profound sense of existential dread. It’s, um, funnier than it sounds. It’s also impressively skillful: the show’s central illusion, that of Lyford and Sobelle repeatedly stepping on and off a silent-movie screen, is seamlessly done every time, even when it involves a member of the audience. (Yes, there is audience participation. Cowboy up.) If All Wears Bowlers is any indication of the kind of conceptually innovative work the other two shows in the rainpan 43 festival will feature – and it likely is – the very least they could be is interesting. That’s a risk worth taking. Studio Theatre, Thursdays-Sundays, Tuesdays, & Wednesdays at 7:30 p.m.; matinees Saturdays & Sundays at 2:30 p.m. $34-$57. To April 20. (202) 332-3300.
