After their critically-acclaimed recording of Mahler’s Fourth Symphony, the Czech Philharmonic and Semyon Bychkov continue their Pentatone Mahler cycle with a rendition of the composer’s Fifth. The Fifth Symphony marks an important turning point in Mahler’s symphonic output, away from the prominence of vocal movements in his previous symphonies. And whereas the Fifth seems to follow a teleology from darkness to light like its predecessors, the trajectory is much less straightforward, and full of enigmatic turns. Bychkov’s exceptional eye for detail and pacing make him an ideal guide through this work, while the Czech Philharmonic is capable of letting all the colours of Mahler’s score shine.
