If you like the idea of a bit of Jay-Z but aren't sure about him being joined by Coldplay and Girls Aloud when he plays Wembley Stadium later in the month, then we think you're a little bit mad. Handily though, your madness is in luck, as Roc Nation have just announced a tiny (as far as Jay Z goes) warm up show for the main man at the Roundhouse on Thursday 17 September. As well as pumping out the old classics, he'll be promoting brand new album The Blueprint 3, which looks like it might score him his first proper UK #1 this weekend with 'Run This Town'. Tickets for the gig are a rather whopping £50 and that's even before you get lumbered with a bellyache full of booking fees. Should you be able to afford that though, there's a sneaky pre-sale with Live Nation on Thursday from 9am, with a public sale here from 9 on Friday.
