Sounds like As the Sparrow used every instrument in the building and a few more they brought with them for their Rubber Tracks session in Studio A. They mention the word swing on their Bandcamp page, and I’m dubbing this stuff Indie Swing… Fiddles, trumpet, piano, boy/girl vocals, drums, guitars – there’s something for everyone. Even what sounds like tape hiss! An instrument you might not hear while your new vinyl is popping and crackling on the turntable.
