Ensemble 42, a DC-based wind-strings chamber music ensemble, will perform Johannes Brahms' youthful Serenade No. 1 on Sunday, March 2 after the 5:30pm Mass. The piece which Brahms later rearranged for a larger orchestra bursts with the energy and passion of the young Brahms, while hinting at the reflective depth of his later years. In the past, Ensemble 42 had also performed the Schubert Octet and the Beethoven Septet, and had also recorded both pieces. The 45 minute concert is free and open to the public.
