The Guardian has an article about the state of the double album these days, and has this very interesting bit about 4:13 Dream:
"I mean, you'd expect the Cure - a band with past double opus form, thanks to 1987's Kiss Me, Kiss Me, Kiss Me - to be able to release a double album, right? Er, sadly not. Their new album 4:13 Dream is the "light" first half of a double collection, with the second "dark" half to be released separately in 2009.
Robert Smith recently told me the rather shocking factors behind the release strategy. Basically, Geffen were only prepared to pay them royalties equivalent to a single album, even if the album was priced as a double. In effect the label were penalising the band for wanting to give their fans more music for less. Smith insisted he didn't care about making any more money but the principle was paramount; he was furious at the idea of a major label conning him out of making the record he wanted. So he held back the second half of the album for six months and one day later, the earliest moment that his contract permitted. The concept would be intact, it would just be up to the fan to Sellotape the two "episodes" together."
And Idolator has an article reacting to the Guardian article.
