Born in Wilhelmshaven, he initiated the concert series Alte Musik Sengwarden/Friesland whilst still a schoolchild. The concert series has meanwhile attracted attention beyond Friesland.
Torsten Johann studied church music at the Hanover University for Music, Drama and Media, where he completed his course with concert examinations in cembalo (soloist class) under Lajos Rovatkay. As a cembalist and continuo player, as well as organ and cembalo soloist and accompanist, he co-founded the Freiburg Baroque Orchestra. His wide-ranging interest in historical music can be seen in, among other things, his constant source studies and regular visits to libraries worldwide.
This work has made him particularly qualified for programme conception and selection involving repertoires of the 17th century. He thus shapes most of the concert programmes of the Freiburg BaroqueConsort.
Invitations to give workshops and presentations regularly take him to the Frankfurt University of Music and Performing Arts.
He founded the summer festival Klassik am Meer in his home town of Wilhelmshaven in 2003, where he conducts scenic and concert works by composers from Reinhard Keiser to Ludwig van Beethoven.
