Kling and Perrin's luminous two-person show is the good news/bad news proposition of this year's Fringe. The good news first. Kling is a masterful storyteller who, in this set, explores the ways human beings deal with two kinds of trouble: the kind that we're born with and the kind that rises up to meet us on the road of life. Funny and, at times, deeply affecting, Kling's vignettes are beautifully crafted feats of observation and memory. They are enhanced by Simone Perrin, a singer who accompanies herself on the accordion. Perrin's voice, while not exactly pretty, is a magically supple instrument and her phrasing is nonpareil. Her "These Boots Are Made for Walking" is an ironic tour de force. The bad news? You have only one more chance to see this exemplary duo. Wednesday, 7:30 p.m.
