No good festivals coming up for me, but this "festival season" does mean lots of gigs coming up from bands that are playing festivals elsewhere... which might actually be a better thing than festivals altogether.
ATP line-up
does look mediocre indeed, but unfortunately it often is... however during the few times that it gets really good (like last December) it's easily the greatest festival you'll ever go to.
From the current "season", Sonic Protest festival looks interesting for those in Paris.

Apparently there's a European edition of the Table of the Elements festival coming up sometime during autumn. Has anyone heard about that?
