For sculpture the space is incredible with dark corners, controlled lighting and a dramatic entry down white spiral stairs.
For music I think it's hard to get the acoustics right. It's a giant sealed box with vertical columns every few metres.
Genesis Owusu tried to make the space work for his sound, presenting a very stripped back version of his best songs. Not sure it worked though. It felt stilted and the tempos were off, when his music is usually boisterous and wild enough to break the floor.
Fun to see the space used differently though. It would work brilliantly for reverb heavy music: The xx or Portishead would be great. Dubby music perhaps?
Though what I really want is a rave in this space. Umek or Speedy J playing dark techno with a monster kick drum and minimal lighting. Perhaps a bit too wild for the Art Gallery?
