Andy Ross may be the most adept ‘60s pop revisionist this side of Aimee Mann, and toning down the cheekiness he displays as a member of OK Go, he brings a more sober perspective to his solo vehicle Secret Dakota Ring. Cantarell, SDR’s second album, is a frequently gorgeous confection showcasing Ross’ pang-tinged vocals and embellished by aching harmonies and lush orchestral arrangements. Underneath the filigree is a solid core of songwriting, combining the elegance of Flower Power-era baroque-pop with a self-mocking lyric sensibility. Ross achieves a bubbly sort of melancholy on “Red Light” and “I Blew Myself Up Over You,” then strolls to a dreamy roller-skating rhythm on “Still Awake.” The string-draped “They Got the Wrong Guy” and the acoustically inclined “I Don’t Wanna Know About My City” wallow in heartache with a wry half-smile. Cantarell sonically swells with the feedback-infused “Send Us a Spaceship,” then shrinks to intimate size for the lullaby-like “Elephants.” Though this is clearly Ross’ show, Travis Harrison’s drumwork adds some needed rock muscle.
