Gesualdo is as notorious as he is celebrated: a prince, a count, a composer and a murderer. He killed his first wife and her lover upon catching them in flagrante -after which an investigation acquitted him because he was a nobleman. Seven operas by composers of the late 20th and 21st centuries are among many pieces inspired by his life and work. His music demonstrates in no uncertain terms the emotional extremity of his imagination, being quite extraordinarily chromatic, dissonant and experimental. That style is exemplified by his first and second books of madrigals, magnificently performed here by Les Arts Florissants and Paul Agnew.
