It is quite a surprise for a dynamic young string quartet to make its recording debut with an album, memento, which takes mortality and death as its theme … But the members of the vision quartet (as that lower-case ‘v’ indicates) like to do things a little differently. The prizewinning Berlin-based players, who appear at major halls and festivals in Europe, North America and Japan, have chosen two works by composers who died in their thirties: Schubert’s ‘Death and the Maiden’ Quartet, and Mendelssohn’s Quartet No 6, written as a memorial to his sister, Fanny.
