This venerable orchestra continues to make special claims to the music of Brahms, and reasonably so, as it debuted the Second and Third Symphonies. This storied band's annual Carnegie Hall residency is devoted to the composer, with the Italian conductor Daniele Gatti at the helm. On Friday, there's the First and Third Symphonies; on Saturday, the Second and Fourth; and on Sunday, the "German Requiem," with the soprano Diana Damrau and the baritone Christian Gerhaher.
