I heard there would be a JamCruise Radio broadcasting on-board the ship. That is awesome. I've enjoyed festival-radioshows from SalmonFest, Bonnaroo, various Ph-estivals, etc. Hopefully they will provide not only information and pre-recorded music, but also pipe some of the live sets through. You know, in case you're on the other side of the ship but you want to chill with the live tunes and your boombox. These shows are always worth recording, too. Great memories.
Plus, radio waves never stop in outerspace. Think of it as providing JamCruise music for aliens.
They could play live & studio tracks by the bands on the cruise, and mix in some other bands from the mainland.
I run a radio show called Honest Tunes on KXUA 88.3 FM Fayetteville. You can listen online every Tuesday night 8-10PM Central time, on http://www.kxua.com
If the radio crew needs any help, I'd be a ready volunteer! email me
