The music of the 17th century is deeply influenced by fearless innovation and bubbling creativity, characterized by experimentation with form that only with the subsequent generation of composers develops into fixed conventions and a higher degree of conformity. Here, a glimpse of the richness represented by the music from the Baltic region in the latter half of the 17th century is presented by bass-baritone Jakob Bloch Jespersen and Concerto Copenhagen under the direction of Lars Ulrik Mortensen. Jakob Bloch Jespersen is in demand as a concert singer throughout Europe, with a repertoire stretching from the 17th until the 21st century. He has a particular affinity for German Baroque music, especially J.S. Bach, of whom he has performed numerous cantatas and large-scale works, such as the B-minor Mass with Danish National Radio Symphony Orchestra/Andrea Marcon, Köthener Trauermusik with Lautten Compagney/Wolfgang Katschner, Saint Matthew and Saint John Passions with among others, Scottish Chamber Orchestra and Wroclaw Baroque Orchestra. In addition, he regularly performs with groups such as Trinity Baroque, Barokksolistene, Leipziger Kammerorchester, Concerto Copenhagen and Arte Dei Suonatori, with conductors such as Stephen Layton, Adam Fischer, Morten Schuldt Jensen, Olof Boman, Paul Hillier, Andrew Lawrence-King, and Lars Ulrik Mortensen.
