The Minneapolis Sound, a variant of funk which emerged in the late '70s was hugely influential on modern music. Not only did it turn funk on its head by replacing horns with synths, making the rhythm section more, well, rhythmic and embracing louder guitars, but from this scene came Minneapolis most famous son. Prince may be the most recognisable artist to come out of the scene, but as this compilation shows, the Minneapolis Sound is still capable of making waves 40 years on.

Purple Snow shows how the seeds of that scene were created and the early experimentation and energy which propelled the music community of Minneapolis forward. As you listen to the album, and read the accompanying book which contextualises the songs, you begin to realise that this was not just a community in name, but in spirit. Musicians would frequently cross bands, collaborate and work as session players. Whilst this compilation pulls together material from before Prince's solo exploits, he does make a couple of appearances, most notably performing with his cousin's band 94 East.

Working through the two discs of Purple Snow, you'll come to realise that the Minneapolis sound, whilst quite easily defined today, was far more fluid than you would expect. Acts like 94 East, Cohesion and Haze certainly adhere to the sound recognised today, but elsewhere you'll see flirtations with soul, influences of jazz and more traditional funk styles creeping in. Horns aren't completely absent either, making appearances and hinting at alternative directions.

The timing of Purple Snow's release really couldn't be better, with several albums released this year mining elements of the Minneapolis Sound. Janelle Monáe, who has made no secret of her love of Prince – to the extent that she features him as a guest vocalist – draws in a number of Minneapolis Sound flourishes. The harmonies throughout Electric Lady are reminiscent of tracks like Haze's 'I Do Love My Lady', whilst the guitar on 'Give Them What You Love' could have been sampled from a number of tracks on this compilation. Listening to Purple Snow as a younger listener - who sadly missed the scene first time around - it is not uncommon to hear passages that could have inspired, and been sampled by, the likes of Daft Punk. Sure Random Access Memories has a stronger disco focus (though it can be argued that even that was influenced by Minneapolis), but the bass lines on Steven's 'Quick' or The Girls' 'I've Got My Eye On You' feel like they could have easily been sampled for another cut on Discovery.

Yet Purple Snow shows these songs don't need updating, or even sampling, to ready them for a new audience. The initial appeal of the Minneapolis Sound has stood the test of time extremely well, and these songs have retained their infectious spirit. It is almost impossible to listen to this album without some of the tracks worming their way into your head; in fact it is difficult not to find yourself up on your feet dancing. Sure, some of the artists featured may have found difficulty in following up the initial burst of creativity, and also survive in the wake left by Prince, but during the period captured by Purple Snow there was nothing more exciting, more alive, and more honest than this.
