Eminem and Outkast will be joining the lineup for the popular festival, Lollapalooza.

According to the Associated Press, Lollapalooza founder Perry Farrell said on Wednesday, "Every year you're shooting to have just an incredible bill that people will look at and say, `I'm there.’ The music is going to entertain them and do wonders for their heart and so is the city."

Farrell created a lineup each year. As Lollapalooza is quite popular, it was no problem finding bands for the festival. According to The Huffington Post, other performers at the festival include Arctic Monkeys, Lorde, Zedd, Interpol, AFI, Calvin Harris, Foster the People, Rudimental, and Nas.

This is the 10th year at Lollapalooza. Last year’s Lollapalooza included The Cure, Mumford & Sons, The Killers, and Nine Inch Nails. Last year’s Lollapalooza festival sold 100,000 visitors a day or 300,000 over a three-day event. The three day passes for the festival are already sold out. One day passes go on sale today.

Bands will perform on eight stages from Aug. 1 – 3.
