I very rarely see named bands anymore. Happy seeing artists like Warrington-Runcorn at Fargo for £13. However, I really wanted to see Shack at the Academy in Brum as they haven't toured for 15 years. That was £40, which was mad.
As for Kraftwerk. Been a huge fan since my teens. Saw them in 1981 and the last time in 1991 at the Hummingbird in Brum. Not bothered in recent years as they are now just a touring machine at big venues. Thought Wolves might be cheapish, but no. Nearly never got one, but well it's a 60th birthday present to myself and Ralf is 80 next year, so won't be many more chances to see them live.
But yes, prices for gigs are absolutely ridiculous now. Fees too. My ticket included £13 in fees and I don't even get a paper ticket!
