“I’m not a backup singer so don’t treat me like one,” Alex Handler sings on the second song from The Taxonomists’s “Dolphin Ape Demo.” Handler is right: one of the band’s biggest advantages is having two vocalists. He and keyboardist Anna Neumann harmonize or trade off, taking the reigns whenever either has the most to add to a song. The five-song EP is catchy as hell, packed with chorus hooks and earworm guitar riffs that will stay in your head for days. “Dolphin Ape Demo” has something from everyone, from crunchy indie pop opener “Phase of the Wave” to its closing track “Play It Cool,” which recalls White Denim’s 2011 ballad “No Real Reason.” Check it out on Bandcamp now – Jake Reed
