Carlos Kleiber was an Austrian conductor born in 1930 who began his conducting career in the mid-20th century and worked primarily in the Western classical tradition. He specialised in Austro-German orchestral and operatic repertoire, maintained a highly selective performance schedule with relatively few public appearances and studio recordings, and was noted for a meticulous, expressive conducting style that shaped interpretations of works by composers such as Mozart, Beethoven and Strauss.
