When do they release the lineup for Jazz Fest?

late december/early january

i'm hoping for big things maybe a little sir paul? mumford to return?

the year before that, it wasn't till january, IIRC. it just depends.

i normally look at some big names on tour and see if they may have skipped a few days late april/early may. that's a pretty good hint, typically. the who are on a tour right now, for instance, and they are skipping the entire area around new orleans. the tour only lasts through feb, but I wouldn't be surprised if there was a reason they skipped NOLA.
