«Es war für mich eine grosse Freude, Anfang Februar 2012 Mahlers 3. Sinfonie mit der Basler Knabenkantorei in Bern aufzuführen. Ein gut vorbereitetes, klangschönes und mit Begeisterung singendes Ensemble!»
«I would just like to congratulate Aaron Mächler for his beautiful singing in our recording and performances of Handel's Athalia (his top notes are still ringing clearly in my ears). It was a pleasure to work with him, and whatever the travel and schedule, wherever we were, he was always happy, positive and professional. He was an inspiration to us all and fully deserved the large applause he received from the audiences. I would also like to thank Markus Teutschbein for his wonderful tutoring and support throughout the project. I wish Aaron great success and happiness in his future.»
«What a pleasure it was working with you all! You impressed everyone else on stage with your discipline, preparation, playful spirit in the Dona Nobis (you were amazing!), and you knocked everyone's socks off because you boys sang from memory! The other choruses were in awe of you! They couldn't do the same! Congratualtions to you all and thank you for making this project so very special for all of us! Martin, you were a true professional, and I wish you the best of luck in your future theatrical and/or musical pursuits.
Markus, thank you for the preparation, for keeping the order in those long breaks, and for keeping the spirit going!
Good luck to you all, and I do hope we will have the chance to work together again in the not-too-distant future!»
«Wir dürfen uns sicher alle freuen über das gute Gelingen des Weihnachtsoratoriums. Das Resultat der Arbeit mit den jungen Sängern ist schlicht bewundernswert, und der Erfolg mit dem tollen Publikumsaufmarsch war verdient! Das Orchester (capriccio basel) hat auch die gute Probenarbeit und die freundschaftliche Atmosphäre sehr geschätzt. Wir danken Ihnen herzlich für alles.»
