The songs released so far from Jeff and Spencer Tweedy’s Sukierae — “I’ll Sing It,” “Summer Noon,” and “Wait For Love” — have been relatively straightforward folk-rock tracks that ostensibly could’ve popped up any time during Tweedy’s two-decade tenure with Wilco. “Diamond Light – Part 1,” on the other hand, is a lengthy experimental excursion that would be more at home on a Loose Fur record. The song tumbles, glides, and skitters through passages that glimmer and skronk with equal frequency. Tweedy’s gentle, familiar vocals show up now and again to lend pop approachability to the bleary sprawl. It’s a fascinating, rewarding piece of music, and you can listen to it below.

Sukierae is out 9/23 on dBpm. A limited edition “Diamond Light” 10-inch vinyl is available for purchase here, and “Diamond Light Pt. 1″ will be available as a free download this Monday for those who preorder Sukierae. Here’s a GIF of the “Diamond Light” vinyl:
