If you live in the Midwest and are younger than 30, there’s a good chance you’ve heard of Lollapalooza.

You probably know something about the music festival. Perhaps you remember that it’s in Grant Park in the middle of Chicago, or that it has eight stages. What you might not know is that Lollapalooza will be the first music festival to offer RFID payment, or that all artists that perform must sign a radius clause. Read on to learn five things you probably didn't know about Lolla.

1. Radius Clause: In order to perform at most music festivals, musicians are required to sign a radius clause. These contracts ban artists from performing within a certain radius of the event, hence the name, for a period of time before and after the festival. Lollapalooza’s clause reportedly prohibits performers from having concerts within 300 miles of Chicago for the six months leading up to the festival, and the three months following. This clause ensures that fans will be craving bands and will be we willing to cough up the dough to buy pricey passes. 
2. Lolla Cashless: Starting this year, Lolla will be breaking ground by incorporating radio frequency identification (RFID) chips into wrists bands, a first for the music festival scene. This will allow festival goers to pay for food and drinks by simply swiping their wristband. The technology spares festival-ers the necessity of hauling around a wallet by allowing the wearer to connect their wristband to a credit or debit card. Don’t worry about somebody stealing you wristband and spending all your money, a PIN created by the user is required with purchases. 
3. Lollapalooza Rules the World: When people mention Lollapalooza, you immediately think of Chicago. But few people realize that Lollapalooza has three other locations outside of the United States. C3 Presents, who own and operates Lollapalooza, also hosts music festivals under the Lollapalooza name in South American nations like Argentina, Chile and Brazil. These festivals south of the border have drawn crowds of over 80,000 on a given day. With such great success exporting the Lollapalooza brand, C3 Presents is reportedly looking for even more sites abroad to host Lollapalooza in the future.
4. Lollapalooza Is on Its Third Life: While Lolla will be celebrating its 23rd anniversary this year, the long lasting festival has hit a number of bumps in the road. Lolla has been canceled twice since its beginnings as a traveling music festival. The first closing came in 1998, but the festival was revived in 2003, only to fold again in 2004. The version of Lollapalooza most people are now acquainted with was created in 2005 when Grant Park hosted the festival for the first time. Since then, Lollapalooza’s popularity has taken off and the event is scheduled to stay at Grant Park through 2018. 
5. Lolla Used to Be Cheap: During its first years, Lollapalooza could not only boast of a great line up of bands, but also of low ticket prices. A ticket in the early 90’s would only set a Lolla lover back about $32, way cheaper than the cool $250 a three day pass cost this year.

To all Lolla-goers, HAVE A BLAST!
