Bach's three sonatas for viola da gamba and harpsichord (BWV 1027-1029) were written around the year 1740. At those time Bach was Thomaskantor in Leipzig and also director of the Collegium Musicum, a chamber music society. Hille Perl was born in 1965 as daughter of a musicologist and harpsichordist. She studied viola da gamba with some of the leading experts in the field of historically informed performance. For more than 30 years she is travelling around the world, playing concerts and recording albums (more than 25) with different groups or soloizing, mostly in the field of 17th and 18th century music. Michael Behringer, born in 1956, studied church music, harpsichord and organ playing. He is travelling the world extensively, giving concerts with Jordi Savall, Musica Antiqua Köln, Hespèrion XX, Freiburger Barockensemble and many more.
