Indie-folk rock band Penny & Sparrow are back on tour and playing Boston in support of their new album, Lefty. The new 20-track album was born in a retrofitted garden shed turned recording space.

There’s a dusty southern influence on Lefty reminiscent of another mid-fi folk duo from Texas, Hovvdy. As Hovvdy have trafficked in slick production in recent years, Penny & Sparrow have also updated their sound on tracks like “Even Keeled.” Penny & Sparrow prefer the best of both worlds however and still deal in vintage tones, such as tasteful saturation and moogy synth flutes on the next track, “Alphabet.” Track-by-track it’s a bit of a whiplash but on the whole it works.

What sets Penny & Sparrow apart from the rest of the indie folk flock is their experimental flourishes. Notice the vocal flutters bringing the ear candy to “Arm Candy.” The fritillary grace notes would be lost however if they weren’t standing on solid ground: distinguished vocal melodies cascade down clever acoustic guitar chords throughout. The more traditionally arranged indie folk songs like “Mattering Ram” pack more of a punch but they do so partly because of the variety and sonic depth of the LP. The result is a gently devastating indie-folk record. I’ll be curious to hear what P & S agree to bring to the stage, and what they decide to leave in the shed.
