Richter/Muti: Schumann Piano Concerto (live) - De Agostini FS96CD01-2
NM / made in Italy
recorded "live" at the Salzburg Festival on 17 August 1972. Coupled with a performance of Mozart's Sinfonia Concertante in E-flat Major K. 364 with VPO principals Gerhard Hetzel (violin) and Rudolf Streng (viola) - also from Salzburg, 27 July 1974. Both concerts were broadcast from the Festspielhaus with Muti leading the VPO. I believe this is the only semi-commercial release of either performance.
