Opera Vivente opens its season with Mozart's indelible Don Giovanni, or Lord Giovanni, as it is being called, since the company performs everything in English. This tale of the lecherous, if irresistible, nobleman whose conquest of European womanhood is thwarted by the one force even he can't outwit contains some of Mozart's most powerful music. John Bowen directs the new production, featuring Christopher Austin and Joy Greene. Jed Gaylin conducts. Performances are at 7:30 p.m. tomorrow, 3 p.m. Sunday and 7:30 p.m. Oct. 2 and 4 at Emmanuel Episcopal Church, 811 Cathedral St. Tickets are $33-$55. Call 410-547-7997 or go to operavivente.org
