Following last year’s fuzzy 12-track Night Cows, Cambridge psych-rock trio FEDAVEES return with a new 7-inch single, Solar Flower, due out in early 2012. Until the wax is pressed, its two spooky, psyched-out tracks (recorded by Carter Tanton of Lower Dens and, formerly, Tulsa) are available for free on their Bandcamp, backed by the local Middlesex-night-turned-music-blog-turned-DIY-label pRIMORDIAL SOUNDS. (They’re the dudes behind new jams from ex-Doomstar!/Ketman project Creaturos as well as the Beat Awfuls.) The A-side, “Self of Light,” is just under four minutes, with a surfy bass line, double-time drums, and a meandering guitar riff; it’s equal parts spacey ’60s garage and contemporary out-there goth-wave grit. The noisy vocals are nearly inaudible under a woozy wall of distorted lo-fi jamming, but the memorable melody sticks. B-side “Freedom Freezes Over” is a reworking of the mid-tempo head-bopper that appeared on Night Cows.
