Fischer’s long-time cello partner, Enrico Mainardi, was also almost an institution in Salzburg, both as master and mentor. In a duo with Carlo Zecchi on the piano, he constructed a filigree arch leading from Beethoven’s op. 102 No. 1 via Schubert’s Arpeggione Sonata D 821 to Brahms’s op. 38, demonstrating masterly control and a superior ability to realize the contrapuntal aspects of the give-and-take of ensemble playing.
