Fest Bump.

Index Fest Adds Girl Talk, Warpaint, Titus Andronicus and More.

Well, Index Festival just stepped its game up.

After its initial lineup announcement back in mid-July, the festival quietly added a few names to its bill last week before going ahead and getting completely nuts-o with today's announcement that Girl Talk, Lucero and Warpaint are slated to now join the two-day October 18 and 19 festival.

Tickets to the multi-venue, seven-stage affair are currently on sale, starting at $48 for a two-day pass.

That's a pretty solid deal, if you look at the bill of bands announced to date below — especially when you consider that Spune says more performers are still yet to be revealed in the coming weeks.
