Ok first off this is my first post and I only made the account to pass this a long so cover your eyes before reading below. I have a client who absolutely knows where they are rehearsing and he owns a specialty shipping business and works for a group who is working for the band. Obviously he is in a ND agreement so I will not say who and frankly the spoiler is not a ground breaking or shocking, in fact it makes some sense. He claims, although not actually seeing them, he heard them rehearse Prelude (hemispheres) several times which morphed into Far Cry There you have it.. How reliable, hes a nice guy and always pays his bill so I have no reason to doubt it. Have a nice day!
