Uptown Special will be remembered for one of the all time great pop singles, “Uptown Funk” featuring Bruno Mars. Ronson’s sound isn’t always so maximalist, and the record revels in its more understated tones and melodies, hugely informed by 70’s Jazz and 80’s Disco. But you can’t deny the pull of a genuine classic single. The album was helped to number 5 on the US Billboard 200, easily Mark’s most successful US release. It’s also the first time he’d struck number 1 in the UK. Ronson told Spin: I always come back to: Stevie Wonder, Chaka Khan, great late-’70s, early-’80s R&B.
