I have seen some concerts here - one of the highlights was Madre Deus and Fela!. Because of the superb ambience and acoustics of the place, many live videos have been shot here. One case in point - a concert of Buena Vista Social Club.
I had the great fortune to perform there in September last year, along with 1,000 voices. It was totally a capella and the acoustics were so great that it was a treat.
The place has been fully refurbished for its 125th anniversary in December 2013. So it looks and sounds amazing.
