Freiburger Barockorchester tours all over the world and records with frequency; it utilizes distinguished guest conductors on about a fourth of its public concerts, but not on recordings. Freiburger Barockorchester contributed some of the very best recordings to be issued by Deutsche Harmonia Mundi in the waning years of its association with BMG. The group's controversial recording of the J.S. Bach Mass in B minor, led by Hengelbrock and featuring the Balthasar-Neumann-Chor, is perhaps the only recording of this work in recent memory to approach Bach's masterwork from a genuinely new perspective. Since BMG folded its classical operation in 1999, Freiburger Barockorchester has appeared on the Virgin, Naïve, Harmonia Mundi, and Carus Verlag labels.
