This July 2018 release is the third of Andris Nelsons' DG Shostakovich Symphony cycle and contains live performances of the 4th [1936, but withdrawn 'till 1961] and 11th [1957] Symphonies. Nelsons is performing his Shostakovich cycle with the Boston Symphony Orchestra.
The first two instalments were remarkable successes, with definitive performances of the 5th and 10th Symphonies. The 5th was paired with the 8th and 9th, the 10th stood alone. To be fair, not much could follow the 10th, what I consider the greatest symphony of the 20th Century. And therein lies the problem with a complete Shostakovich symphony cycle. Of the fifteen symphonies, I think six (1, 4, 5, 7, 8, 10) are masterpieces interspersed with lesser patriotic or dramatic works, and even a couple of jingoistic duds (2 and 3).
