Collegium 1704 is a Czech early music orchestra and choir founded in 2005 by the Czech conductor, harpsichordist, and horn player Václav Luks. The Collegium Vocale 1704 is the affiliated vocal ensemble. Since 2007, the ensemble has been making regular guest appearances at festivals and concert halls all over Europe: the Salzburger Festspiele (2015, 2016, 2018), the Berliner Philharmonie, London’s Wigmore Hall, Vienna’s Theater an der Wien and Konzerthaus, the Lucerne Festival, BOZAR (Palais des Beaux-Arts) in Brussels, the Chopin Festival in Warsaw, Wratislavia Cantans, and the Elbphilharmonie, and it is an ensemble-in-residence at the festival Oude Muziek in Utrecht and at the Leipzig Bachfest. In 2008, Music Bridge Prague — Dresden began, bringing together the two cities’ wealth of cultural traditions. In 2012 Collegium 1704 started a concert series at the Rudolfinum in Prague. Since autumn 2015, the two cycles have been merged into a single concert season that continues to take place in parallel in Prague and Dresden. In 2019 Collegium Vocale 1704 launched a series of chamber choir concerts in Prague. wikipedia
