The rules are simple:
The first SoundClasher records a 20 minute sequence using any audio they like, and send it over to the second SoundClasher, who records their 20 minute response. Then it goes back and forth once more, until there's an 80 minute show, which is released as a podcast.
The great listening public then votes on which SoundClasher they think won, and whoever gets the most votes gets to stay on against a challenger and do it all over again.
We managed four of these shows on
TheCoolestRadioEver, and hopefully there will be more in the future.
