As if writing about music wasn’t hard enough, we feel the need to somehow label and classify it. like biologists do the flora and fauna. In less complicated days there was classical (orchestral), jazz, rock, pop and folk/country, but as music grew into an industry (as in business) those genres developed their own sub-genres and sub-sub-genres, then fusions and hybrids of those genres. With that in mind, trying to come up with a generic label for last night’s gig at the (O2) Brixton Academy was a bit tricky. Urban (whatever that means in musical terms) or MOBO would probably cover it in broad terms, but whatever it was, it was some of the best of what London and Britain has to offer, and Brixton, the home of Soul II Soul, was a fitting venue for it, even if most of the acts were from North London.
