Go on, choose. You can have anyone at all, bands or solo artistes (living or dead - though obviously to avoid any Shaun moments you may prefer to imagine that they were alive to be performing).
When first asked this I said I would go for Pulp (recapturing the spirit of the Highbury garage gig), current faves Misty's Big Adventure (because they'd be a hoot) and The Arcade Fire (because on current sell-out popularity I have about as much chance of seeing them as sneaking into a suitcase to NYC!)
On another day it may be Ballboy (who have always been good VFM live), Godspeed You Black Emperor and Ella Fitzgerald (now THAT's what I call an eclectic musical lineup).
If I can go back in time, a good point in Bobby Dylan's career, alongside Bruce Springsteen and Randy Newman would be good.
Oooh... how about a bit of Charlie Mingus, with some Nina Simone followed by... ooh, change of direction... Bjork?
On a different track again ... how about Vladimir Ashkenazy playing Rachmanov's 3rd Piano Concerto, the Birmingham Symphony Orchestra doing Mahler's 5th (I have memories of a broadcast version that was much better than the Berlin one Rattle conducted) and some Sigur Ros?
Gosh, too many things to consider! But thanks to Paul W for the prompt!
