Anthony Bean Theater has extended the run of August Wilson's The Piano Lesson (reviewed in Gambit this week). In Wilson's cycle of plays chronicling African-American life in the 20th century, The Piano Lesson is fourth in the sequence and deals with the legacy of slavery. Family members differ over breaking with the past or preserving a link to their history, in this case a piano that was once traded for two of their relatives. The instrument's inner panels are carved with the likenesses of past ancestors. But selling it might provide the money to invest in a venture that could support the family into future generations. Wilson won his second Pulitzer Prize for the play. The final performance is at 3 p.m. Sat., Oct. 3 at Anthony Bean Community Theater, 1333 S. Carrollton Ave., 862-7529).
