Though the big guns which are at the Edinburgh Fringe have now been rolled out, it’s taking some time to pin down what to aim for there. Meanwhile its somewhat smaller sibling is continuing in Camden and so I thought I would take a break from Edinburgh brochure browsing and pick up on a couple of shows from a Festival which is much nearer geographically and boasts some interesting online content. My choices narrowed down to a pair of performances which took ecology as one of their central themes.
