15. Voivod, 'Target Earth'
No way Target Earth should have worked as well as it does. 32 years in, these French-Canadian prog-metal titans make their first album since the year 2005 death of guitarist Denis "Piggy" D'Amour and bring back O.G. bassist Jean-Yves "Blacky" Thériault. It should have exploded on takeoff. And yet, boom, Earth annihilated by planet-busting riffs and the band's signature, recombinant touches — head-scratching thrash, knuckle dragging dirge, elliptical structures, and singer Snake's deep-focus odd streak. Long may they rrröööaaarrr.
