I/O is the tenth studio album by the English singer-songwriter and musician Peter Gabriel, released on 1 December 2023 through Real World Records. It is Gabriel's first album of new original material since Up, marking the longest gap between studio albums in his career. I/O features 12 tracks, each with two different mixes labeled the "Bright-Side Mix" and "Dark-Side Mix". It is also Gabriel's longest studio album of original material, with the mixes clocking in at over 68 minutes each and the total project lasting over two hours. An additional "In-Side Mix" of the album appears on versions which include the Blu-ray audio disc, which brings the total of the entire project lasting over three hours. I/O had been in the works for nearly three decades, with its initial production dating back to April 1995, at around the same time Gabriel began recording Up. He began planning the follow-up to Up as early as 2000 and had originally intended to release it in 2004, but the album was repeatedly delayed, reworked and re-recorded at seven recording studios before its completion in December 2022.
