Wang (humanities, California State U.) studies six of Wilson's plays, including The Piano Lesson , Seven Guitars , Ma Rainey's Black Bottom , and Fences . He treats each play separately and examines the thematic strands running through them, especially as the relate to the struggle of African-Americans to come to grips with their history, their place in American society, and their struggle for a just society.
