Mozart once played on a baroque organ (27 December, 1769), found in Chiesa di San Tomaso Becket, Verona, Italy. Last Friday night, I went to a concert there to hear Mozart music. Amazing.
The small group of musicians and the organist all sat up high in the balcony that you see here. The music echoed beautifully through the large structure of the church.
As a keyboard player (piano), I appreciate this all,and enjoy the history as well.
Here is a link to more info on the church (but in Italian)
