"South London rapper follows up Mercury-winning debut with modest, unambitious second album" is not a line you'll read about this explosive new record from Speech Debelle. If you're worried about a deficit of political anger in contemporary British music, listen to "Blaze Up a Fire", the track she leaked in August in response to the UK riots, or "Collapse", which describes with manic intensity the geopolitical road to global anarchy. Debelle is not always easy company and can veer into self-absorption, but the album is refreshingly outspoken and, with help from producer Kwes, musically daring.
