Heifetz, Primrose, and Feuermann Play String Duos and Trios (Biddulph). Jascha Heifetz, who needs no introduction, made a fair number of chamber-music recordings in the Forties with Emanuel Feuermann, the greatest cellist who ever lived, and William Primrose, one of the greatest violists. This 1993 collection (out of print but easy to obtain) contains their dazzling 78 versions of Dohnanyi’s C Major Serenade and Mozart’s E Flat Divertimento, plus duos for violin and viola by Handel-Halvorsen and Mozart. No matter how long you live, you’ll never hear finer string playing (TT).
