When Markus Stenz and the Gürzenich-Orchestra play their Prom, history will be telescoped in a unique way. Not only will this richly historic orchestra – whose past conductors have included Mendelssohn, Wagner, Verdi, Brahms, and Stravinsky – recreate the programme their predecessors played in Cologne in 1904, at which Mahler's Fifth Symphony was introduced to the world; they will also rework that concert's Schubert element, and will celebrate Cologne's greatest 20th-century musical son by performing Stockhausen's Punkte.
