Originally a collaboration between producers Diplo and Switch, Major Lazer's 2009 debut (the excellent Guns Don't Kill People . . . Lazers Do) featured the likes of Santigold, Amanda Blank, and Vybz Cartel.
There was something of a sea-change after Switch left: 2013's Free the Universe still included some less- obvious collaborators (Dirty Projectors' Amber Coffman), but also featured more commercial artists and sounds.
Peace Is the Mission expands on that further. The cutting-edge production is still there. Lean On features a great vocal from MØ, Roll the Bass is a moody take on rave culture, and Light It Up pleasingly mingles dancehall, 1990s r'n'b and 8-bit.
But Be Together is too silken, and there are missteps with vocalists (such as Ellie Goulding on the syrupy Powerful). There is so much potential here.
