Pianist Mitsuko Uchida and violinist Mark Steinberg have been playing these sonatas together for 12 years now. Their playing is as natural as breathing.

Choosing just four must have been a difficult task. The result is remarkable, giving us a sweeping portrayal of the depths Mozart was able to find within this most honed-back of all chamber ensembles.

The first two (K377 and K303) are relatively optimistic and playful pieces, although even these give glimpses of the depths Beethoven would later plumb in this genre.

But Mozart finds his own emotional depths in the work in E Minor, K304, written just after his mother died. This is a surprisingly bleak and sorrowful composition, devoid of the sunlight which flows abundantly from most of his work.

The final quartet, in A major K526, was written much later and is a far more complex work showing the composer’s full artistic maturity. It is as important a work as anything he composed, intense and dramatic, though with abundant joy and light. Our two performers grace these compositions with lucid, intelligent playing; and the warm, intimate recording serves them with distinction.
