Grainger's 'At Twilight' showcases his unique harmonic language, blending impressionistic colors with his idiosyncratic folk-inspired sensibilities. The writing is dense and requires sensitive ear work.
The primary challenge is layering the voices to maintain the clarity of the atmospheric harmonic shifts.
