Razor-sharp string chords, oscillating sound images and groovy piano rhythms: this is how the Flex Ensemble begins its first GENUIN CD and Stephen Hartke's ‘The King of the Sun’ piano quartet, followed on by works of Piazzolla (‘Three Devil Pieces’) and Brahms’ third and final string quartet, the C minor, op. 60. + One of the most vibrant ensembles of their generation whose courage and artistic sovereignty has been critically praised, the Flex Ensemble’s dedication to the major piano quartet literature is complemented by their wide-ranging artistic collaborations and compelling programs.
