How much of the last six years has been spent working on these seven new songs isn't known, but every second was worth it. Don't be fooled by the sparse tracklisting; the disc clocks in at over 65 minutes, making up a dense, daft, delightful record based around the white stuff.
Where to begin? There's back-to-back songs about getting it on with a snowman ('Misty') and a yeti ('Wild Man'). The former is over 13 and a half minutes long and chucks up a much sexier version of Raymond Briggs's tale, despite the equally-inevitable sad ending (I can feel him melting in my hand / Melting, melting, in my hand").
Obviously those who find Bush too self-consciously quirky aren't going to be won round by the sound of that, but the problem with 2011 pop is all-too-often the lack of pretension, rather than an excess of it. First person lyrics from the perspective of a snowflake ("I was born in a cloud / Now I am falling / I want you to catch me") beat a po-faced, try-hard grope of "authenticity" any day.
Bush tops off the wonderful madness with the title track, where she implores Stephen Fry no less, in character as "Prof. Joseph Yupik", to come up with 50 different expressions for snow. Our favourites are "swans-a-melting", "slipperella", "erase-o-dust" and "mountainsob". Another fine hook-up comes with Elton John duet 'Snowed In At Wheeler Street', a tale of love lost, regained and grasped close in terror.
Understated, organic instruments gorgeously frame Bush's snowy stories, showcasing a unique voice which sounds as good - if not better - than ever. While it'd be a shame to wait another six years for the next batch of new material, the truth is we'll probably still be spinning this come Xmas 2017 anyway.
