Unless Andris Nelsons is intending to record “Die Nullte” (the D minor symphony Bruckner composed in 1869 between the first and second numbered works), this will be the final instalment in his cycle with the Leipzig orchestra, which has unfolded in parallel with his Shostakovich series across the Atlantic in Boston. Like the previous instalments, the performances of the First and Fifth Symphonies are taken from concerts in the Gewandhaus over the last three years, and like the previous instalments, too, the set is bulked out with bleeding chunks of Wagner, in this case the Prelude and Liebestod (without the soprano soloist) from Tristan und Isolde.
