Having worked with Superfrog for nearly 4 years as their artist/creative director, I have developed 3 different web sites for the band, along with a variety of marketing materials.
This was the first site I created for the band. It implemented an audio player embeded in a secondary web page loaded by frames so navigation throughout the site allowed for listening to the music to be uninterupted. The framework of the site was HTML with a full flash interface embeded as the primary site. It is long gone from the web, however, a version is available on this server.
You can see the live version of the site here.
