This orchestra and conductor have, with other partners, recorded Sibelius symphonies previously. But this set finds all parties besting their respective prior efforts. The vaunted richness of Berlin’s string section often plunges Sibelius into gloriously foreboding territory—right where he should be. For being cut live, there’s a persuasive unity to each of Rattle’s interpretations. There will always be debates about the best Sibelius cycle—favoring perhaps more prototypically Nordic readings—though this strong release is a worthy entrant in the 21st century’s Sibelius revival sweepstakes.
