Kevin Parker is a real enigma of a musician. The brains behind the rightly celebrated and ever-surprising Tame Impala, he's never one for delivering quite what you expect, while still understanding that one of the most important things in music is striking a balance between the familiarity disciples need, and the expressive exploration that can prick the ears of the previously uninitiated. Album number four, "The Slow Rush", certainly adopts a different outlook to previous undertakings. It also more than lives up to its name. It's smooth, tripped out (perhaps not so surprising on the latter front) and strikingly void of those highs that seem to offer the aural equivalent to some opiate-amphetamine blend. But we don't miss out. Instead, we're given permutations of soul, prog rock and acid house, perhaps making for the most expansive record this guy has been responsible for.
