Tennis have slipped out a couple of songs this summer, and each has been a super lo-fi/pop gem in its own right. Underwater Peoples will release a 7” from the duo later this month that collects a couple of those tunes. You may have already heard “Marathon”, the sparkling, throwback pop b-side, or seen the video for “South Carolina”. If not you’ve been missing out. Now check out “Baltimore”, the vintage sounding collage of jangly guitars, big booming drums, and Alaina Moore’s sweet-as-salt water vocals that kicks the thing off (via Pitchfork).
