The harpsichord may conjure images of men in wigs and ornate drawing rooms of times past, but Mahan Esfahani has made it his life’s mission to rehabilitate the instrument, bringing a rock star quality to both the keyboard and the music. Esfahani makes his NWS debut in this chamber music concert, which begins with a quartet by harpsichord-enthusiast C.P.E. Bach. In Oophaa, Iannis Xenakis brings the instrument into the future by amplifying and pairing it with two percussionists, who jam on flowerpots. Critics called Henryk Górecki’s whirlwind Concerto a veritable volcano and a spectacular plaything. Considered the Father of the String Quartet, Joseph Haydn broods in D minor. A suite of choral works by Heinrich Schütz is arranged for brass by NWS’s own Michael Linville.
