During his long partnership with EMI, at the end of his conducting career, Otto Klemperer produced numerous Beethoven records that are still absolute references and a legacy of his musical genius. Along with major symphonies from his stereo complete cycle, this album includes concertos with Yehudi Menuhin and Daniel Barenboim, overtures, and excerpts from his milestone version of Fidelio, with Christa Ludwig, Walter Berry and Jon Vickers.
