I don't know what prompted this--declining revenue from the sale of CDs and downloads, a desire to close things out properly, or some other need, artistic or otherwise--but it does mark a fundamental change for Kate Bush to schedule a series of live concerts.
As in, holy hell, Kate Bush is going to actually get up in public and sing.
There's no doubt that she can pull it off, but a proper backing band will need to bring her into the 21st Century as far as playing live is concerned. She's going to have to put something in her ear and try to sing--can she pull it off? I would think that she could.
Now would be a good time to figure out which luminaries from British music will show up. David Gilmour should, and why not Peter Gabriel? Beyond that, someone is going to have fight for tickets.
