The main focus of the programme is JS Bach’s Goldberg Variations, which Armstrong reads with assurance, refinement and a maturity beyond his years. His sound is pearly, highlighting the work’s lyricism, and tempos are beautifully judged for the hall’s ample space…Above all, though, he builds the music’s architecture.

Armstrong has the ability to reduce his sound to the merest whisper while retaining projection; intellect is completely in the service of music. The Aria unfolds absolutely naturally, while the immediately following music reveals Armstrong’s rock- solid rhythm. Armstrong’s mastery of tone, his ability to project the most tender expression and his long- range vision contribute to a stunning performance.
