In the most trying of times, the Round House Theatre has managed to put together a pretty remarkable season, entirely online but leaning on one-person showcases that eliminated the need of distancing among cast members. They perform on fully dressed theater sets (instead of a Zoom window), before a minuscule audience, either to bolster the actor or provide laughs in the spaces needed. As with previous offerings this season, the streamed presentation of Lucy Alibar's "Throw Me on the Burnpile and Light Me Up" begins with the few audience members, in masks and face shields (and sometimes masks and face shields) entering the lobby and getting their tickets torn. Just 10 people were allowed to see Beth Hylton's performance live for the two performances filmed last month.
