Noise-rock behemoths Swans’ final record of the 20th century—they would go dark for the next 14 years—broke sharply with the rest of their ’90s output, in part because it’s essentially a Michael Gira solo project. Far from its pummelling predecessors, this ambitious double album is a fever dream of electronic sketches interwoven with found sounds and Dictaphone remnants. Bits of full-band jams and cacophonous live scraps peek through the fog, only to be swallowed up by the ambient swirl. Swans’ most experimental project, it’s a heady, enveloping listen, while the odd rave-up—like jet-engine loud “Blood Section”—reminds us that they’re among the world’s heaviest.
