7. Meshuggah – Ronnie James Dio Stage - Saturday, August 12th – headliner!!.

Hats off to Bloodstock and that admirable intent to not recycle headliners. Sending Sweden's tech-metal masters to headline status is a stroke of absolute genius. If you haven't experienced the sheer latent power of Meshuggah live, then boy you are in for a treat.

This is metal at its most primal but also simultaneously at its most complex. When you strip it down there is actually very little here but it is orchestrated in such a way that it feels cosmic and infinite.

They dispense with all the finery and all those distractions and concentrate on creating a tsunami of driving, penetrating riffs that pulsate into your frontal lobes. This is metal taken to a transcendental dimension, full of angular tones and relentless rhythmic beats. It really will be quite extraordinary.
