Opera in flux

Here’s your chance to partner with Mozart, Bizet, Verdi, and other opera legends — and they’ll never know. At OperaHub’s “Choose Your Own Opera Adventure,’’ you will be given two or three choices about how a plot should end, so brush up on your knowledge of “Faust,’’ “Marriage of Figaro,’’ “La Traviata,’’ and other masterpieces. Pictured (from left): David Wilson, Nina Moe, and Darian Worrell. Tonight at 8 and 9:30 p.m. (through Oct. 31 at different venues; reservations recommended). Free. VFW Hall, 371 Summer St., Davis Square, Somerville. 617-821-8515. www.operahub.org
