Costa Rican indie rockers Las Robertas love the swirling feedback of classic British shoegaze, along with the sun-kissed pop that ruled the beaches of California in the '60s. Waves of the New is the trio’s catchiest fusion yet, even if they still drench their sugary retro hooks in glittering lo-fi noise. They bash away with glee on “Alto Astral,” blending the blare of My Bloody Valentine with the bubblegum of The Beach Boys, but they also slip into blissful reveries like “California Feeling,” dialing back the distortion to craft a beatific surf-rock anthem. Lush and loud, Waves of the New mixes chilled vibes with visceral thrills.
