Review: The concept behind Friction's Vs series is simple: hook up with as many mates in the studio as possible and write straight-up floor-flatteners. No theme, no pretention, just talented producers working together and playing off each other's strengths. Following epic co-labs with the likes of Icicle, Technimatic and Total Science comes the fattest edition yet as the BBC broadcaster teams up with Dimension (hooky and euphoric), Prolix (outrageously nasty and techy), Metrik (unabashed evangelism with a very well-known vocal hook) and Ulterior Motive (old school references wearing new school armour). Each one repping all player's finest attributes, Friction has brought out the best in his peers... And his own work. Essential.
