The…oboe… had a loyal benefactor in Bruno Maderna. The Italian composer's three concertos show him keeping unshakable faith, expanding the instrument's expressive spectrum and devising orchestral timbres and structures that ingeniously telescoped outwards from its acoustic fundamentals. German oboist Fabian Menzel clearly relishes the rare opportunity to explore these seminal works, and the alert backings of the Saarbrücken RSO have been caught with pristine clarity from mainly live performances.
