Eleven albums in, and LA’s grizzled funk-rock reprobates are tinkering with the formula. The Getaway is the Chili Peppers’ second album with newish guitarist Josh Klinghoffer and their first since 1989 without producer Rick Rubin: Brian “Danger Mouse” Burton is behind the faders, introducing Beatley nuances on Feasting on the Flowers and a little unexpected disco sparkle on Go Robot; Nigel Godrich mixes – a hook-up born of bassist Flea’s sojourn in Atoms for Peace. Fans will probably find The Getaway an improvement on 2011’s I’m With You, citing tunes such as Detroit. Sceptics will continue to boggle at their enduring charmlessness, a problem not even Danger Mouse can fix.
