Google search for "Michael Sanderling Shostakovich Review" brings up several, including MusicWeb and Gramophone, which cover various earlier releases combining items from Sanderling's complete cycles of Beethoven and Shostakovich, matching the two Fifths, the two Firsts, the Ninth and Thirteenth, plus the Third and the Tenth. Not raves by any means... nothing yet on the complete 15 I could find.
