Note: The poster textures have been clumped together in one single texture for the final version. The separate textures can be found inside 'venues\basement\textures\gen'.
The snake poster can be seen in the 'Making Guitar Hero Characters' video at 10:30 and the Flyer texture can be seen in the same place in the 'Making the venues' video at 10:20. It is also used as the texture for Axel Steel's highway.
The posters were most likely meant to be seen on the walls, and were not part of the actual wall itself.
The police car was originally meant to be seen behind the right window while the lights flash blue and red. The car is visible in the prototype, however.
The red texture was originally meant to be in the Freak Pit venue, as seen here. It was later replaced with a blue version. The red banner can still be seen in the final version if you play the multiplayer mode.
The arcade cabinet and jukebox do not appear in the final build of the game. They can be seen on the right side of the screen here at 2:51. A pinball cabinet can be seen in the concept art in the 'Making the Venues' video at 1:53.
The bathroom door does not appear in the final build, however two door cutouts can be seen in concept art in the 'Making the Venues' video at 1:50 and 1:53. The bathroom door can possibly be seen here at 3:35 on the middle-left side of the screen.
The Budeiser Banner and curtain texture do not appear in any pre-release footage, but it is worthy to point out that the Budeiser Banner does use the same effect and color as the red Harmonix banner. It is safe to assume that the banner was cut pretty early in development.
The 'dude' texture has no model associated with it, nor is it known where it would appear. This may be just concept art, as seen in the 'Making the Venues' video at 1:56.
The Exit sign texture can also be found inside the files for Red Octane Club. In this venue it would appear above the exit doors, which earlier in development were on the opposite side of the venue. It can be seen here at 3:31. The model for the exit sign can still be found in the files, and it is hidden behind a wall in this venue. It does not use any textures, however.
The Fen Cab texture has no model associated with it, and it is not known where it would appear. It looks to be a really early or possibly even a concept texture.
This texture suggests that at one point in development, you could customize your 'hero'. This idea was possibly used in Guitar Hero II, where you can select different versions of your character, but full character customization wasn't implemented until Guitar Hero: World Tour.
This is an unused menu texture, however its purpose is unknown. Another texture in the game shows this with artwork of Axel Steel on it (Seen below). This could possibly be an early hero selection screen.
This track, *Trippolette* by Andraleia "Andi" Buch (credited under her deadname), was cut from the game because, to quote a designer who worked on the games, it was "snuck onto the disc by someone in QA without the dev team knowing until too late. Needless to say, [s]he doesn't work at Harmonix anymore." However, Buch has stated multiple times publicly that this was untrue, that the developers failed to clean up the unused files, and that she asked for permission to release the codes given below. Buch herself has been kind enough to set up a page with codes for every device out there to replace the song "Guitar Hero" with Trippolette. It is also possible to hack the game to add it to the setlist alongside the other songs, or to import it into the Guitar Hero 2 engine.
The in-game name for the song is "advharmony", which is taken from what it was derived from: Buch's Advanced Modal Harmony final project. In the September 8, 2005 prototype, the song is entitled “Advanced Harmony: Final Project”. The presence of this song on the prototype's songlist, with full metadata, casts doubt on the cited claim above regarding the track being "snuck onto the disc".
The following is a list of codes for various devices and formats. Trippolette will replace the song "Guitar Hero".
Oddly, the author of this track isn't listed in-game, though Harmonix has reported that an employee named Aaron is the author of this song. The September 8, 2005 prototype lists an artist name of “Gurney”.
The following is a list of codes for various devices and formats. Graveyard Shift will replace the Song "Sail Your Ship By".
