"Transcendental" might be the best way to describe the experience of listening to the music of space-rock duo Windy & Carl. For those not familiar, the Dearborn, MI couple have been recording blissed-out paeans to distortion and delay for nearly a decade now. This particular triple-disc retrospective amasses nearly all of their non-album output released to date. Early handpainted 7" singles showcased on the first disc favor conventional song structures and lyrics, while the material on discs two and three leans toward endlessly spooling vistas of feedback and glorious noise. Their affection for each other and the music is clear, making this collection a testament to the duo's labor of love.
