Schönberg’s orchestration of Brahms’ “Piano Quartet in g” is so convincing, for me it equals the original version.  I love the whole piece; but, for the the first two movement are preludes to the “march” in the Andante con Moto; only to be followed by that rip-roarin’ Rondo.  It a testament to Schönberg’s insight that he should pick this one chamber work of Brahms and see how it almost cries out to be orchestrated.  And such a brilliant orchestration it is.  It’s virtually Brahms’ 5th symphony.
