18 B Sides + DVD is a compilation album by American electronic musician Moby. The album's first disc is a CD featuring nine B-sides from his 2002 album 18, as well as four new songs. The second disc is a DVD featuring a live concert at the Pyramid Stage at the Glastonbury Festival on June 29, 2003, various outtakes and studio demos taken from the Play and 18 studio sessions, a megamix with eleven remixes of six different songs, and music videos for five singles from 18. The DVD also contains an additional non-musical feature entitled Highlights from Moby TV, consisting of several short skits.

18 is the sixth studio album by American electronica musician, songwriter, and producer Moby. It was released on May 13, 2002, by Mute Records in the UK and on May 14, 2002, by V2 Records in the US. After the unexpected commercial and critical success of his previous album, Play (1999), Moby started to write songs for a follow-up during its supporting tour. He started work on the album at its conclusion in December 2000, using fewer samples than before. Guest vocalists include Azure Ray, MC Lyte, Angie Stone, and Sinéad O'Connor.
