"Simple Mess" is a heart-rending ballad on DEC3's debut self-titled album. The song was written entirely on an acoustic guitar by DEC3's main songwriter, Jon Haber. In our interview with Haber
, he recalled the tracking process for the song. "When I went to record it, I just played through it on an acoustic guitar and that's the actual guitar that's on the record. I never re-did it. I just played it through one time," Haber joked. "Probably the only thing I played without having to pop something in to fix a mistake."
Haber also played bass on the tune and the electric guitar. The piano part was recorded in Nashville, Tennessee by Shane Keister from the pop act Five for Fighting.
