While Sleepy Sun’s first release, Embrace, takes a revivalist approach to psychedelia, the San Francisco outfit’s latest effort, Fever, steps out of the ’60s and into the digital realm of the neo-psych movement. The hazy distortion, meandering guitar riffing and wailing vocals still prevail, but they are tempered by male/female harmonies and simply strummed guitars that make for a distinctly poppier sound. Comparisons to Black Mountain are apt — Rachel Williams’ tremulous howl is a ringer for Black Mountain’s Amber Webber — but Sleepy Sun’s syrupy, lazy cadences often prove a more laid-back response to Black Mountain’s thundering call to arms. With Sleepy Eyes of Death, Wilildlife. SARA BRICKNER
