-Die entführung aus dem serail with Klemperer (EMI, 1973)

For February 1973, EMI planned a recording directed by Otto Klemperer with Lucia Popp (Konstanze), Ileana Cotrubas (Blondchen), Werner Hollweg (Belmonte), Werner Krenn (Pedrillo) and Hans Sotin (Osmin). At the last minute the director decided to cancel the project, because he no longer wanted to make more opera recordings. To 'employ' the John Alldis Choir and the New Philharmonia Orchestra, EMI decided to record the Mass in C minor of Mozart, KV 427, with Ileana Cotrubas, Kiri Te Kanawa, Werner Krenn, Hans Sotin and Raymond Leppard.
