Hear your sounds played in the Reverberation Chamber at the National Physical Laboratory

CloudChamber will play your music in the above room, record it in stereo and send you a link to the result. You can listen to all of their uploads so far here: https://soundcloud.com/cloudchamber-co - a lot of them sound very muddy, but there are some cool ones. Drum breaks sound especially awesome.
