Okey poke:
Aloud.com listed gigs:
London: 750
Manchester: 261
Birmingham: 164
Glasgow:104
Edinburgh: 25
Though to be fair to the towns which aren't London,
most of the gigs are like
BANDNAME
london
london
manchester
birmingham
etc, and having the same gig twice is no indicator of a better scene. Also, big name bands playing isn't an indicator of a big scene either, Manchester for example has the jilly's rockworld allnighter, 4 big floors of hardcore all night, several nights a week. This is probably an unrivalled thing, but doesn't appear on aloud.com
