If you're a fan of Solar Year, chances are you may have heard some version of this album already, since it's been knocking around for the best part of a year. You probably won't have heard it like this, though; the Canadian electronic duo decided that their debut album needed some spit and polish - as in, a whole new remixing/remastering job, as well as the addition of some new material. Far from just being distributed around their native Montreal, Waverly deserves a much wider audience. After all, when a track featuring Grimes proves to be only the tip of the iceberg, its creators must surely be on to something good.

At its core - if you strip away everything - the record is a fairly conventional take on atmospheric, poppy electro - you could imagine someone like M83 penning a song as delicately beautiful as 'Abby & Amber', for example - with some sonic experimentalism thrown in here and there. However, the album relies on its spacey production and ambitious sound for the full effect. The music tells only half the story - it's what's been done with it that's equally as remarkable. For instance, 'Night and Day' is a straightforward, mid-tempo pop song, but the vocals have been treated in such a manner that they're all but unrecognisable; the melodies float up as if from underwater; beats that would normally be crisp and precise are instead forced to take a back seat. The pair - Ben Borden and David Ertel - take on electro-pop music and flip it on its head; that Grimes collaboration ('Brother') is every bit as wispy as Claire Boucher's own material, and twice as unpredictable, erupting in a tremendous explosion of gritty noise just as it seems ready to fade into nothingness.

Even though it may sometimes seem impenetrable, as the listener wishes for the duo's sound to open up and is frustrated at almost every turn, multiple listens allow for the record to do just that. It's not exactly stubborn; 'Seeing the Same' and the insistent 'Lines' show that while the pair may sometimes be wilfully obtuse - they describe themselves as 'psalmgaze' on their Facebook page, for example - they can write some damn good hooks when they put their mind to it. With Waverly, persistence is the key - what initially seems ghostly and intangible eventually reveals itself to be downright beautiful, and as soon as 'Pivot' thumps and clicks its way to a close, you'll want to dive right back into Solar's Year's strange and fascinating world.
