The 2oth anniversary of the Ottawa Fringe Festival is now underway. Covering a massive undertaking like the Fringe requires some agility. ARTSFILE’s theatre writer Patrick Langston has covered as many bases as he could over the past few days offering his takes on up to a dozen shows in this year’s lineup. As Langston knows, you never know what you are going to find at the Fringe. Here is his take on four shows currently on view. They were seen on Sunday.
