One song on the album stands out though, besides being incredibly heart-wrenching, honest, and captivating, the song O'Sister (found below) also touches on mental health. Through the song, Green delves into his sister's struggles with generalized anxiety disorder (GAD), and shares his guilt for being away on tour and not being there to support her.
Green's sister Jordan, further discusses her diagnosis and experiences with GAD, as well as how music has helped her to recover in an article for the St. Catherine Standard, which can be found here: http://www.stcatharinesstandard.ca/2011/10/13/music-heals-me-says-dallas-greens-sister-jordan
