There is a beautiful film from 2014 in which harpsichordist, Ton Koopman and Melchior Huurdeman take us on a tour of the Thomaskirche and the Bach Archives in the town of Leipzig. There, they retrace the steps in the church where Bach’s St. Matthew Passion was performed for the first time.
The film is in German and English subtitles are available. Enjoy it here.
