The German baritone, Johannes Kammler, graduated in 2008 from the Music High School at St. Stephan in Augsburg, and went appreaed there several times as a bass soloist with arias and Lieder at school concerts. Already at 5 he began a thorough musical training with the Augsburger Domsingknaben. With the vocal support of his father, Domkapellmeister Reinhard Kammler, he sang as alto several times at the Deutschen Oper am Rhein Düsseldorf, the 3rd boy in Mozart's Zauberflöte, in many foreign concert engagements including The boy's solo in Leonard Bernstein's Chichester Psalms, the boy's solo in Orff's Osteroratorium at the Münchner Prinzregententheater, many alto arias in J.S. Bach's oratorios and cantatas and a CD recording of Engelbert Humperdinck's Hansel und Gretel as Hansel in Abendsegen (Evening Prayer).
After the change of his voice until 2009, Johannes Kammler had singing lessons with Ulrich Streckmann, vocal trainer and choir director of the Augsburger Domsingknaben. In their traditional Bach concerts, his father entrusted him soon with the major solo bass roles in Weihnachts-Oratorium (BWV 248), Johannes-Passion (BWV 245) and the B Minor Mass (BWV 232). On the CD of the male voices of the Augsburger Domsingknaben "Gott und die Welt" and on the CD with Otto Jochum's Weihnachtssinge his young bass voice is also heard on solo. With the Kammerchor der Augsburger Domsingknaben, Johannes Kammler has performed as alto and bass in numerous concerts in Germany, other European countries and in Canada, Ecuador and South Africa.
Since winter 2009-2010 Johannes Kammler is a student at the Musikhochschule in Freiburg majoring in singing with Professor Markus Goritzki.
