Rollercoaster (lost unreleased songs from Red House Painters album; existence unconfirmed; 1990s)
Rollercoaster is very widely considered Mark Kozelek's masterpiece album. Like many Kozelek related productions, the project went through many changes and has a lot of missing material. Unlike a lot of the other albums whose material has either been bootlegged or at least confirmed by the singer-songwriter, the missing tracks of Rollercoaster have yet to be acknowledged. Their existence may very well have validity, however.
Rollercoaster was one of two self-titled Red House Painters releases from 1993. The other album, Bridge seems to have lyrical content that was very close in nature to that of Rollercoaster. In truth, both albums' material is from the same exact recording sessions. The two albums were originally conceived as a double album in the vein of Led Zeppelin's Physical Graffiti or Pink Floyd's The Wall.
Then there's the strange fact that many fans have claimed to have heard some lost tracks that were intended for the Rollercoaster album. This is not as farfetched as many would claim it to be. Old Ramon was meant to be a double album and has confirmed missing tracks. Kozelek has never been asked about these tracks, so the validity of this album, even containing lost tracks, is still unknown. Nevertheless, the production behind Rollercoaster remains an enigma to many music historians as Kozelek almost never goes into great detail about its production.
