One of the most politicised albums you're likely to hear. M.I.A.'s mixtape (co-produced with Diplo), 'Piracy Funds Terrorism Vol.1', of late last year best hinted that 'Arular' was going to be quite an event. In just forty minutes, M.I.A. has produced a mix of hip-hop, ragga, dancehall, electro and, dare we say, punk.
