Loft Opera is a new company whose Don Giovanni last spring was one of the more engaging productions of this complex work I have attended in years. The youthful cast was superb and the stage direction remarkably effective. I loved how boundless ingenuity, rather than complicated scenery and production values, resulted in an incisive performance that also had immense charm. The troupe returns with Le Nozze di Figaro (Nov 7-9), an opera that poses even more staging challenges. They will again appear in a loft near Brooklyn’s Gowanus Canal. The audience will sit among the performers. What window will Cherubino jump out of?
