If anyone is interested, does not know already In Clapham Common there is a Calling Festival (replaces the Hyde Park one). Main act on 28th is Aerosmith and more to be confirmed. Tickets are about 70GBP for both days so not that bad.
I will, it is better then Rihanna, all the other R&B or HippidiHop artists or those most of the new "Rock" bands that just make Pop music only. BTW Metallica has a new song that is part of new album coming out in future and it is good.
