If, by any chance, any Hauptwerkians just happen to find themselves in Stockholm, Sweden, at 3pm on 31 October, you're very welcome to drop in at the Museum of History on Narvavägen 13, where Hauptwerk will be played by yours truly in a performance of Duruflé's Requiem (version for choir, organ and cello). I will also be performing Olivier Messiaen's "Dieu parmi nous" as a solo.
The sample set used is Sonus Paradisi's Cavaillé-Coll organ from St Etienne, Caen. The sound system is an 8 channel, 4000 watt system provided by http://stageroom.se.
It was very nice meeting you, P-O, at the concert. Always nice to talk to other Hauptwerk users. Thanks for showing up; looking forward to hearing more about your theatre organ project.
