Live concert concert in London

Hi Host Community, I am producing a concert in London and I need help with several important aspects of the event. This is going to be a fantastic show and I want to make sure everything is perfect. I need a full sound system that can handle a large venue, and accommodation for the artists who will be performing. The concert is scheduled for next month and I'm reaching out to the community for support. If you have any equipment available or know of great accommodation options near the venue, please let me know. Your help would be greatly appreciated! Looking forward to hearing from you. Best regards, John
