King of choirs

The Choir of King's College, Cambridge, is one of the most famous in the business.

Viola makes five

When writing their string quintets, Mozart and Brahms added a viola to the basic string quartet of two violins, one viola and a cello. Violist Coca Bochonko joins the Mill City String Quartet for Mozart's Quintet in G Minor and Brahms' Quintet in G Major, both masterpieces of the chamber repertoire.

Notebooks of da Vinci

Minneapolis composer Jocelyn Hagen marks the 500th anniversary of Leonardo da Vinci's death.

The piece features text drawn from da Vinci's writings. And the concert features motion graphics starring the artist's own drawings (projected using very cool digital synchronization software).

Scaling new heights
