Alive in the Superunknown was Soundgarden's first multimedia
effort, issued on the relatively new (at the time) CD+ medium. CD+ allows both
standard audio tracks and multimedia clips to exist on the same
disc. While all audio CD players can read the CD+ wth no problems,
there are some CD-ROM drives that are unable to recognize the
format. Hence, the CD+ comes bundled with a CD containing Corel CD+
drivers for Windows 3.1x and Macintosh System 7.x.
Please note that there is a possibility that your CD-ROM drive will not be able to read the CD+ if is more than a few years old. For example, be aware that Creative Labs' 2X and 6X drives do not support CD+ and the company has made it known that they do not plan to write drivers for the format.
The standard audio tracks included on the CD+ are as follows:
The multimedia portion of the CD Plus (developed by nu.millennia) contains the following:
The liner notes include complete installation instructions as well as troubleshooting guidelines and ways to reach technical support.
The minimum system requirements for running the CD+ are as follows:
The artwork at the official website (which is what you see below) is not the cover, but the "main menu" of the multimedia portion of the CD Plus. Clicking on the upper left would take you to the video forest, the upper right would take you to the photo jam, the lower left would take you to the audio player, the staircase would take you to the Superunknown, and clicking on the skull exits the program.
As you may already know, the official Soundgarden website has its own CD+ promo (with lots of dazzling server push-pull stuff). Also, check out Polygram Records' page for info, a couple of sound clips, and a 32-second video clip.
The four regular audio tracks that are on the CD+ were also made available on an audio-only EP that was released the same day, called Songs From The Superunknown.
