On this new release, Ton Koopman has gathered together every one of Bach's cantatas. Finally reprinted after some years, this is a must-have reference collection. Antonius Gerhardus Michael (Ton) Koopman is a Dutch conductor, organist and harpsichordist. He is also professor at the Royal Conservatory of The Hague. In April 2003 he was knighted in the Netherlands, receiving the Order of the Netherlands Lion. Koopman's Bach Cantatas project is the most ambitious project of his career. He finished the project in 2005.
