Since its establishment, the J. S. Bach Foundation has worked with internationally renowned vocal soloists. The artists are selected under careful consideration of the musical demands and other requirements of each work – usually two years in advance of the concert date. Throughout the years, Rudolf Lutz and his advisors, Ines Volpert (2006-2016) and Xoán Castiñeira (since 2017), have developed a vocal concept that is distinguished by high clarity of diction, interpretive skill, purity of intonation and discreet vibrato. Versatility, timbral quality and the best possible match between voice and music guide the process for engaging artists.

In addition to working with established soloists, the artistic director is committed to fostering and developing talent within the ensemble. Outstanding choristers are regularly given the opportunity to perform solo, usually starting with small parts. Over the past 20 years, members of the ensemble developed by Rudolf Lutz and his assistants have embarked on notable solo careers.
