Duran Duran's 13th studio album from 2011 All You Need is Now, was produced by grammy award-winner Mark Ronson and mixed by Spike Stent. It featured guest vocals / rap from longtime Duran Duran pal / collaborator Ana Matronic of the Scissor Sisters and r&b / neo-soul superstar Kelis; while Owen Pallett of Arcade Fire contributes the album's string arrangements. All You Need is Now was a return-to-roots homage to Duran Duran's most celebrated musical panache, which has already been dubbed by its producer as the 'imaginary follow up to Rio that never was.'
