“Psychic Trauma” is not only the name of the new song from the Cloud Nothings, but it’s also how you might feel once the steady, even-keeled track — spoiler alert! — transforms into a completely different song at the forty-five second mark. In one quick step it accelerates from pleasant, low key, low-fi rock to driving, blasting, cymbal-crashing punk. It’s a fantastic little bait-and-switch in which the switched-to tune is far more engaging, compelling, and raucous than the bait. Stream it below.
