When we weren't looking, Calvin Harris became one of the most influential artists on the planet.
Now everyone's on the blower to the boy from Dumfries, hoping to get some of that Euro-rave magic, and here – on his third album – he gets to call on guest stars including Rihanna (their We Found Love collaboration is included), Kelis, Dizzee Rascal, Ne-Yo and Ellie Goulding. All this and Tinie Tempah too.
Not to mention Example, who pops up on clash-of-the-rave-titans number two hit We'll Be Coming Back, and Florence Welch, on number one single Sweet Nothing. It's an astonishing roll-call, but Harris's personality isn't subsumed by all this talent. The guests end up charismatic adjuncts to his dancefloor smartbombs as 18 Months passes by in a delirious flash.
Indeed some of the finest tracks are all Harris's work, from the air-punching soul-house anthem Feel So Close to crazed acid throwback Mansion, and when the unstarry Ayah Marah provides a gorgeous vocal for classic deep house closer Thinking About You the album hits its peak.
It's a cracking finish to a record that sustains its quality over 15 tracks and justifies Harris's new-found status. That phone's going to be ringing off the hook.
