Was this a Corinne Bailey Rae audience or a Somerset House audience? “We’re Somerset House fans,” I heard one posh punter proudly tell some friends. Then later I heard a woman talking about the Florence and the Machine gig that she’d missed earlier in this short season of concerts, as if it were a stamp missing from her collection. Could this really be an audience who were here for the building first and the music second? Yes, this enclosed yet open-air square in central London is a delightful space, but when did ambience become more important than music? And anyway, there’s no space on Earth that could make Florence and the Machine sound good to me. But Corinne Bailey Rae, now that’s a different matter.
