In a 2006 interview with Verbicide Magazine, band members were asked if a new remix album would be produced for Demon Days as there was for Gorillaz. They answered that it was a possibility and that might involve the Spacemonkeyz again. In the same interview, they were asked if there might also be another G Sides. Again, their answer was that it might be possible. In January 2007, websites began listing a March release date for a Phase 2 B-sides album. One of the websites, musictap.net, later pushed this back to 3 April. According to Gorillaz-Unofficial, the reaction of official parties behind Gorillaz is that the release date is just a rumour for now. On 29 August, musictap.net reported that the B-side album would be titled D-Sides and would be released on 20 November. On 18 September 2007, the official Gorillaz fansite confirmed the release of the album, as well as unveiling the album artwork and track listing. D-Sides was released on 19 November 2007 in the UK and on 20 November 2007 in the U.S. The song "Rockit", like many songs on the album, was intended for inclusion on the Demon Days album, though was later pulled from the tracklisting. "People" is an early demo version of "DARE", which doesn't contain as many instruments and does not include Shaun Ryder on the track. The album features a reworking of the song "Hong Kong", which was originally featured on the War Child charity album Help!: A Day in the Life; this newer version adds a string section and studio effects to the previously sparse arrangement.
