? (XXXTentacion album)

? is the second studio album by American rapper XXXTentacion and his last studio album to be released in his lifetime, three months before his death. It was released through Bad Vibes Forever, Caroline Distribution, and Capitol Music Group on March 16, 2018, and primarily produced by frequent collaborator John Cunningham, it includes a wide range of guest appearances from PnB Rock, Travis Barker of Blink-182, Joey Badass, Matt Ox, Rio Santana, Judah, and Carlos Andrez, and also succeeds the release of his debut studio album 17 (2017) and the extended play A Ghetto Christmas Carol (2017). Featuring more live instrumentation than 17, ? features an array of genres, including acoustic, emo, alternative rock, trap, and cloud rap. XXXTentacion's vocals on parts of the album are less restrained and lo-fi-ish compared to 17, with his vocals on introspective songs over piano and acoustic guitar chords being more projected. On other parts of the album, XXXTentacion's style resembles his underground sound, with him screaming. The album was supported by three singles: "Sad!", "Changes", and "Moonlight".
