Playcrafters Barn Theatre's Blues for an Alabama Sky manages to be an adjective I've come to love regarding theatrical productions: surprising. Playwright Pearl Cleage takes her story in directions I did not expect from the outset of Saturday's performance, as her play moves from the plight of a recently out-of-work singer in Harlem to a study of societal views on homosexuality and abortion in 1930. I had no idea that was the direction the plot would take, but I was grateful for it, as the proceedings kept me on my mental toes, and continually interested in what was going to happen next.
