The session two days before, however, is adventurous in musical terms too - a rare convergence of four leading string quartets. At noon the Taliesin plays, followed by the Balanescu at 3.00pm, the Alberni at 5.30pm and the Brodsky at 8.00pm. Repertoire includes Mozart, Beethoven and Schubert as well as pieces by Britten and Carl Vine and some of the Balanescu's new collaborations. Nigel Kennedy and Friends play on 24 May, and on the 23rd there is Stephen McNeff's 'thriller opera' for Modern Music Theatre Troupe, The Waste Land (not Eliot's words, but about them).
