Johann Sebastian Bach, touring widely with the Gächinger Kantorei and the Bach Collegium Stuttgart and often introducing the music in talk concerts. The talks included music examples by all performers, making the music accessible for all kinds of listeners because specialist terminology was "translated" immediately into sounds.

He became the festival conductor and lecturer at the Toronto Bach Festival in 2004. He continued to lead the Gächinger Kantorei and the Bach-Collegium Stuttgart until 2013, and retired from conducting concerts in 2018. Rilling died in
