We die. It doesn’t take an astrophysicist to figure that out. But last year, a CD thus titled—Morimur—rocketed up the charts and sold an astronomical number of copies. It also demonstrated that radical interpretations of J.S. Bach—who died some 252 years ago—remain artistically and commercially viable. Morimur uses the Partita D Minor for Solo Violin (BWV 1004) as its centerpiece, particularly the funereal chaconne movement, which commemorates the death of Bach’s first wife, in 1720. A series of lush vocal arrangements performed by the renowned Hilliard Ensemble demonstrate that Bach utilized some of the same melodies in a number of chorales. Morimur intersperses those earlier liturgical pieces with Christoph Poppen’s rendition of the partita to produce a stunning fusion of Bach’s most mournful compositions. Yet despite the immense popularity of the recording and the basic beauty of the work, it’s not often heard live. Well, now’s your chance: On Saturday, the Hilliard Ensemble and Christoph Poppen will perform Morimur at 8 p.m. at St. Columbia’s Church, 4201 Albemarle St. NW. $20 (suggested donation).
