Otto & Astrid: The Stages Tour is a thunderously funny, musically brilliant, and strangely moving 70-minute masterwork that explodes like a glitter bomb in a wine-barrel basement. Berlin’s most charismatic dysfunctional siblings ignite the sold-out UNDER St. Marks audience into helpless laughter, communal sing-alongs, and genuine warmth. Clare Bartholomew and Daniel Tobias are performers of extraordinary caliber. Do not miss them. Wherever they play next, follow them there.
