Power animals, happy places, imagined fields of cool wet grass – these are all concepts familiar to Korn and their cartoonishly dysfunctional frontman Jon Davis. Depressingly entitled Hold On (really boys, LET GO), this, their latest serving of heavy metal self-help, harks back to their glory days of snarling, detuned glory but updates the template with anthemic vocals and a surprising amount of melody. The band are trying hard, but unfortunately Korn's best ain't what it used to be, and Hold On ends up sounding like just another post-Linkin Park dilution of metal's diminishing gene pool.
