Unofficial Recordings Artists Kleiber: Die Fledermaus Overture Rehearsal & Performance, South German Radio Symphony Orchestra (now Stuttgart Radio Symphony Orchestra), 1969 & 1970 ★ In the performance, Kleiber delivers a free and improvisational performance, but in the rehearsal, he gives careful and delicate instructions, repeatedly pursuing the sound with a tenacity that borders on the divine. The highlights include his instructions to the orchestra, especially for the ultra-fast passages and the sweetly sung melodies with rubato. Kleiber's voice at 39 years old is enough to make your heart leap. Beethoven: Symphony No. 7, Cologne Radio Symphony Orchestra, May 1972 ★ This live recording still has the power to excite listeners today. The explosive force sweeps the listener away, and those who surrender to this force experience both a sense of happiness and fatigue. It is a great stroke of luck that the concert recording in Cologne remains. It is rare to experience such a direct and captivating performance, along with Carlos Kleiber's fiery performance and his outstanding sense of style, in other recordings.
