Grievous Angel is the second and final solo studio album by Gram Parsons, compiled from summer 1973 sessions and released four months after his death from a morphine and alcohol overdose in September 1973. Prominently featuring a young Emmylou Harris, Grievous Angel received great critical acclaim upon release but failed to find commercial success, a fate shared with Parsons’ previous efforts solo and with The Flying Burrito Brothers. Grievous Angel peaked at number 195 on the Billboard charts. Despite its modest sales, it is viewed as a successful example of the hybrid between country and rock and roll Parsons called "Cosmic American Music". 

GP is American singer-songwriter Gram Parsons' debut solo album, and the only one released during his lifetime. It was originally released in a gatefold sleeve in 1973. GP received critical acclaim upon release, but failed to reach the Billboard charts. In the original Rolling Stone review, which individually covered both GP and its follow-up, Grievous Angel, the reviewer praises Parsons' vocals and delivery paraphrasing Gram's lyrics, "boy, but he sure can sing".
