Scholar Charles Rosen has described the Sonata No. 11 in B-flat major, Op. 22 (composed in 1800) as Beethoven's 'farewell to the eighteenth century'. It was, for the composer, the culmination of the stylistic idioms of the classical era, as well as the pinnacle of his early four-movement 'grand' piano sonatas. This performance is taken from Daniel Barenboim's highly esteemed complete rendition of Beethoven's 32 piano sonatas, recorded at the Palais Rasumofsky, Vienna, Austria, in 1983.
