Looks like Denton's Oaktopia festival is shaping up to be an indie band magnet. And the big names just keep coming.

On Aug. 4, Oaktopia announced that University of North Texas alumna and Grammy Award-winning singer/songwriter Norah Jones will return to Denton to headline the festival. 

The announcement comes on the heels on last month's jaw-dropping news that Beirut, Cat Power and Dallas' Erykah Badu, as her behind-the-decks persona, DJ Lo Down Loretta Brown, would also play. (Check out the full list at the bottom.)

Back in June, the festival, which is slated for Sept. 22-24, took to Twitter to tease its initial lineup, posting clues and asking followers to guess the performing artists. Like this:

Founded in 2013, Oaktopia spawned from a desire to keep Denton music on display year-round, according to co-founder Matt Battaglia. It's debut coincided with the year another prominent festival in the college town, 35 Denton, took hiatus. In fact, this year's Oaktopia lineup even resembles 35 Denton fests of years passed -- Dr. Dog played in 2011 and Best Coast played in 2012.

In its first two years, Oaktopia grew from 40 to more than 120 bands, of which about 100 were local to North Texas. The festival sets up outdoor stages as well as utilizes several music venues around the square, such as Dan's Silverleaf. Last year was the best installment so far, with sets from indie greats Edward Sharpe and the Magnetic Zeros, funk maestro Thundercat and retro rockers Bright Light Social Hour.

Tickets are currently on sale in three tiers: $50 for single-day passes, $85 for three-day general admission, and $200 for three-day VIP, which includes a T-shirt, free drinks and food, and access to an exclusive seating and festival after party.
