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".

Ingram Cecil Connor III, known professionally as Gram Parsons, was an American singer, songwriter, guitarist, and pianist. He recorded as a solo artist and with the International Submarine Band, the Byrds, and the Flying Burrito Brothers, popularizing what he called "Cosmic American Music", a hybrid of country, rhythm and blues, soul, folk, and rock.
