This may be the year of Ben in Philly, but it is also the 250th anniversary of Mozart's birth, and in fact the lives of the two giants touched one another; Mozart wrote the single most ethereal piece of music for Franklin's glass armonica. Our local musical venues are not exactly overflowing with Mozart, but there is a good dose of it this weekend. The Ama Deus Ensemble, directed by Valentin Radu, devotes an entire concert to the genius from Salzburg, with a program that neatly hits three distinct periods of his short life. They open with what is generally considered his first mature masterpiece, the motet "Exsultate Jubilate," written when Mozart was a teenager. The centerpiece is his "Jupiter" Symphony, written when the composer was at the height of his creative powers, and certainly one of the finest examples of musical craftsmanship in the history of the art. This is, by the way, one of at least three performances of this piece locally this year, but it is hard to imagine another work of music so immune to overexposure. The finale, in every sense of the word, is the Requiem, a work so loaded with legend and lore that it is nearly impossible to avoid the notion that Mozart, who was still writing it on his deathbed, penned his own mighty swan song. If you happen to be in Devon Sunday afternoon, check out the superb playing of the Philadelphia Trio. This is the last concert of their current series, and includes music by Schumann, contemporary composer Robert Sierra, and for the birthday boy, the Mozart Sonata in B flat for Violin and Piano.
