Royal Albert Hall appears to have finally sorted its acoustics and sound system issues. I’ve never seen a show there, but I’ve heard many live albums from progressive rock artists who have played there. Most of those recordings sound like garbage because of the physical environment in which they were recorded. Hopefully this new system they have will remedy the 150 year old problem.
