Polyrhythm Is a Weapon - virtuosic, airless, knotty, where jazz fury and prog architecture collide at the extreme edge. It opens in Mahavishnu's molten jazz-rock fire, moves through the Canterbury dissolve of Soft Machine and Henry Cow's splintered chamber-rock, into Gentle Giant's madrigal-meets-odd-meter trickery and National Health's piano-dense peak, then down into Univers Zero's pitch-black Belgian chamber assault and Magma's zeuhl Coltrane-ritual enormity - Porcupine Tree live as the bridge to metal, closing on Meshuggah's 23-against-4 riff, the logical terminus of everything before it.
