Actually, it will already be the third edition this Zappa Festival in Larvik, Norway.
I'm not 100% sure, but I think that it's a two-day-event, and that it will be on Friday 2012/02/10 & Saturday 2012/02/11.
Latest news says that the following bands are expected.
And they'll all be playing the music of Frank Zappa...
* The Norwegian brassensamble
* Muffin Men
and special guests Ike Willis and Denny Walley
