About

Chamber music, up close

Impromptu Concerts was founded on the idea of creating a chamber music series that offers the finest possible acoustic experience. Chamber music is at its most compelling in an intimate setting, where audiences can feel a direct connection with the performers and the music, rather than observing from a distance.

Since its inception, the series has presented more than 25 performances, featuring talented musicians and a rich chamber music repertoire.
