Short and oh-so-sweet—like sugar on top of presweetened cereal— comes Johnnyswim’s debut Heart Beats. However, there’s also plenty of crunch to the musicality of husband-and-wife duo Abner Ramirez and Amanda Sudano. Guided by their pop instincts, the pair composes songs that stick in the head, mixing unshakable dance grooves forged from rhythm and blues, rock, blues, bolero, country and folk, often pulsed by insistent beats, handclaps and choruses rising from the dust. Amanda’s rich vocals hover above it all, sometimes complemented by Abner in classic call-and-response fashion or via potent dual harmonies. Their Nashville influence shows on several tracks, notably the stripped down, acoustic “Adelina.” A mere 22:35 long, the pair creates a unique stylistic hopscotch that calls out for more.
