For his 80th birthday, Ton Koopman has chosen some of his favourite tracks from the many recordings he has made for Challenge Classics / Antoine Marchand since 2002. This is a celebratory collection in four parts: music for organ, for harpsichord, chamber music and recordings with the Amsterdam Baroque Orchestra & Choir. Ton Koopman: "It was, of course, an almost impossible task to draw up a selection from all of the CDs I have recorded for Challenge Records, but I have tried to choose works that are very close to my heart."
