After 10 years of presenting touring chamber groups within the Indiana History Center, Ensemble Music has moved (while the IHC undergoes a scheduled six-month refurbishment). What the new Central Library's auditorium lacks in the visual aesthetics of the IHC's shoebox-shaped Basile Theater with its beautiful wood inlay, it makes up for in slightly brighter timbres and a bit more bloom -- a wider but shallower venue. The Brentano Quartet experienced these new acoustics along with the rest of us in a program containing contrasting, if not quite first-rate, fare. Predictably, Haydn opened the program: his Quartet in G Minor, Op. 20 No. 3, a mature, well-crafted work with many rhythmic pauses that was well-handled by our players. Next came a 12-tone (serial) work of Arnold Schoenberg, his Quartet No. 4, Op. 37 (1936), epitomizing Raymond Leppard's assessment of Schoenberg after developing his serial technique: "He blew it!" All 12 notes of the chromatic scale are heard in no particular order but the arrangement, remaining constant throughout, produces no tonal harmonies, no harmonic tension/resolution and abrupt endings of all four movements, as though Schoenberg just ran out of notes. Let's face it, connoisseurs: The emperor was naked. Relief came to us in the second half with Schumann's Quartet in A, Op. 41 No. 3 -- the best of his three in the genre. Excellent craftsmanship in the Romantic vein prevailed. In all three works, the Brentanos displayed better balanced tonal characteristics than the Belcea Quartet of a month ago. www.ensemblemusic.org.
