Hi,
There is only an official demo for the Maria Strassengel ambience, and it is a very extreme one. I like it (and the piece) very much, but would like to listen to some more musical situations with it.
The church is very often used for the musical life of Graz. In general, it looks like a gothic church should be and sound. It has that magic floral shape that makes the stone look a lot like something organic. While I'm more accustomed to romanesque churches with no bays on the roof (the typical architecture of my area), it's the kind of church environment I should feel more connaturate to me, belonging more or less to the same age, and conceived more or less for the same music.
Then, the late gothic shape of Strassengel is quite familiar to me, looking so similar to the main apse (the "German chapel") of the Basilica di Loreto. I don't know if they sound really similar, since Loreto has a huge (and hugely resonant) chatedral on the open side, but the roof has two bays past the apse, and this is where the typical gothic church sound develops.
So, I would be happy if someone can identify other demos (or post other pieces) placed in that little church. I'll listen them with a great curiosity. And comparison with the sound of Pernegg would be very interesting.
Paolo
