Skewed Visions has built its reputation on creative, immersive, site-specific theater. The company’s current work, by company co-founder Charles Campbell, roams through three houses on Cambridge Street in St. Paul’s Mac-Groveland neighborhood. 3-Minute Egg follows the players from house to house in a run-through rehearsal and talks with Campbell about how a mere stage has never worked for him. Performances run through the end of the month.
