Other official releases
Internal Bleeding released a few recordings that were either compilations or "preview" releases. Some of these are easily available, while others are much harder to find.
Alien Breed (2001): Was a release put out by Olympic Recordings in 2001. It is a compilation of all three Internal Bleeding demos. It includes copious liner notes describing each demo and classic photos of the band's lineups. It included one new song "Alien Breed," which never made it to an album.
Pure American Fury (2002): A two-song demo preview of the Onward to Mecca album. Recorded in a home studio and released by the band. This was meant to be a teaser type of promo. The cover was a simple color photocopy. It includes the songs "Bleed by Example" and "This Day I Fight". Less than 100 of these promos were made, making it the rarest of all the band's releases.
Heritage of Sickness (2011): Since the original release of Internal Bleeding's demos, time, technology and the scene had changed greatly. To celebrate the reformation of the band, they released this compilation of the band's classic demos, which also contained bonus live tracks recorded at the Mountains of Death festival in Switzerland. This release features incredibly cleaned up versions of the demos. Only 1000 copies were made and some copies are still available through the band and select distributors.
Beside these official releases, there are also extremely rare "promo only" releases of the band's first two demos that were given to fanzines and other media. These releases are incredibly hard to find, and production numbers are unavailable.
