Science Fiction PC Speaker is a polyphonic PC speaker tribute to The Rocky Horror Show which combines all the worst aspects of 1980s video game music with everybody's favorite musical/sci-fi/sex/horror-comedy! All of the songs are represented including Once In Awhile and other material which was cut from the movie.
Most people are probably going to want to check out The Time Warp first since it's the most well-known, well-liked song in the soundtrack, but I recommend Sweet Transvestite or Dammit Janet instead because they sound more like the songs you're used to. The Time Warp is still The Time Warp, but after the first verse it gets a little weird on purpose. I tend to get bored with that song, and this was the only way I could convince myself to finish it.
Anyway, check it out. Really. This took me a long time and I'm looking for validation. I'll even make it easy for you by putting another link to the album right here.
