Just to note, its not only Astoira + Astoria 2 which will be demolished. Metro round the corner on Oxford Street will also close, and the block of buildings opposite Astoria next to Centre Point will also be demolished, which includes the club 'Sin'.
So a total of four music venues to be lost in one fell swoop.
I've also heard that, despite some campaigns, they just silently went ahead with approvals to demolish the Electric Ballroom in Camden.
Honestly, I cant think where all these extra small/medium bands are going to play now.
