Iris Rieg plays: 'O Mensch bewein dein Sünde Groß' by J.S. Bach.

The talented German organist Iris Rieg plays 'O Mensch bewein dein Sünde Groß' by J.S. Bach on the Johannus Ecclesia D-450. This video was recorded in the Ss. Cornelius und Cyprianus church in Lippetal, germany.

The five members of the Johannus Ecclesia family take choral singing and congregational singing to a higher level.

In its own unique way, each of the five different Johannus church organs takes the lead in polyphonic singing.

Modest and decided, almost inaudible and majestic, rustically romantic and exuberantly baroque: the Ecclesia is an instrument with the feel of a church organ in every fibre.
