I'd love to hear your recordings... I play a lot of Dead (and the like), am a future Further owner, and kind of starved to hear the sound!
You can use Soundcloud, and people can follow you to find out when there are new posts. You do not have to convert to mp3, but if you wanted to, you can do it easily in iTunes, QuickTime Player, or many other applications.
Looking forward to the gig report!
