Thanks leeneia - all good points.

This is where I normally run concerts. http://www.faldingworthlive.co.uk/ where INHO we have a very good set up.

The problem I have with the room in the pictures is the height of the ceiling and the awkwardness of the room. Just wanted to find out if it would work. Plus I doubt if I can have a stage, which then makes it difficult for the audience to see the artists properly.

"4. Try not to have the sound too loud." I am with you entirely. That is one thing I am a stickler for.
