Anyone with a passing knowledge of the Red Bull company could be forgiven for thinking that their raison d’être is, firstly, to sell caffeinated soft drinks and, secondly, to sell more caffeinated soft drinks. Apparently this is not the case. The Red Bull company exists to rock out, party hard and give up-and-coming young musicians wings. At least that’s the impression their press release gave me. I had come to a nondescript building near London Bridge to find out what sort of musicians would sign up to be part of a rock brand.
