Seven Guitars: Watching M Ensemble's latest production is like sitting in your neighbor's back yard on Sunday. Although there's not a lot going on, simply being invited generates a feel-good sense of belonging. But after spending an hour listening to strangers jabber about their lives without any real story line, you might begin to wish you were someplace where there was something to get excited about. Written by the late, great August Wilson in 1995, Guitars is one work in an epic ten-play cycle that chronicles the twentieth-century black American experience. As with many of Wilson's works, Guitars is staged in a tenement in Pittsburgh's notorious Hill District. The play opens at the wake of Floyd "Schoolboy" Barton, a blues guitarist/singer. After the mourners briefly contemplate the loss of a friend, the audience is transported back in time to witness the events that led to his unnatural death. Although Guitars is rife with dialogue that easily ebbs and flows like the ocean, the dull and shallow plot dilutes the play's overall success. But to the credit of the slow-moving story, the characters are some of the most well developed ever to step onto a stage. Joanne Green Through May 28. M Ensemble Actor's Studio, 12320 W.
