Meshuggah: "Demiurge"

Almost feels like the rise of the lyric video is already starting to make these performance clips obsolete - in an expense vs reward kinda way - but with Scion A/V footing the bill Meshuggah went ahead and knocked out this belated single from an album that's been out since March. Isn't it already time to start thinking follow up?

Meshuggah: "Break Those Bones Whose Sinews Gave It Motion"

Meshuggah are the Tool of extreme metal. They may not be as accessible to the average modern rock radio junkie, but they come from a similar ethos of mixing moody, progressive riffs with deliberately off-putting, fragmented time signatures. Hopefully the guys in 'shuggah don't decide that they need their own analog to A Perfect Circle to vent their more mainstream (read: sellout) predilections.

By the way, this video sucks. Just listen to the tune and shut the fuck up.

Vildhjarta: "Benblåst"

Måsstaden, the debut album from Swedish prog metal merchants Vildhjarta, has got to be one of the more hotly anticipated releases of late 2011.  Vildhjarta are loosely influenced by and often compared to countrymen Meshuggah, but a quick listen to "Benblåst" shows a little more going on in the experimental realm.  At just over three minutes, roughly 1/3 of which is an atmospheric intro, this serves as little more than a teaser of what's to come when the album hits on 11/29.
