Organ music

last night I found the time to go to a lovely Organ music concert free of charge. I cant remember what songs the player played, but the sound was beautifull. The concert was in a lovely church (can't find one in a concert hall), so everynote he pressed just echoed for a while in the church, and the church it's self was amazing, with nice archetechture and windows, and I throughly enjoyed. so advice to anyone out there: if you like relaxing music, classicle music and have a concert near by, it is a great opportunity (especially if it is free of charge) to discovor this music before it dissapears in history (like middle ages music).
