In four concerts, ALL THE WRONG NOTES: Charles Ives at 150 celebrates the 150th anniversary of composer, keyboardist, actuary, and businessman Charles Ives.

This second concert on Oct. 25 features all four rarely-heard Violin Sonatas, performed by guest violinist KJ McDonald and DMA pianist Ariel Mo. Rhapsodic and inventive, rich with references to the popular tunes and cultural settings of New England, these sonatas showcase the whirling imagination and fearless complexity of Ives’ writing, but is also replete with moments of deep-seated nostalgia and optimistic humanism that even “soft ears” can appreciate.
