The 2012 iHeartRadio Music Festival is only a couple of days away. What better way to get ready for the performances than with a look back at 2011?

Last September, Ryan Seacrest declared the 2011 iHeartRadio Music Festival to be "the biggest live music event in radio history." The first-time event sold out in just a few minutes — a legacy that continued to this year's festival, which is scheduled to start on Friday, Sept. 21.

This year's lineup boasts a who's who of music, including Rihanna, Brad Paisley and Taylor Swift. Last year was pretty packed with stars, too; Alicia Keys, Jay-Z, Carrie Underwood, Steven Tyler, Sting, Nicki Minaj, Rascal Flatts, Bruno Mars, Usher and Kenny Chesney all performed for 25,000-plus screaming fans at the MGM Grand in Las Vegas.

Jennifer Lopez

Singer and actress Jennifer Lopez was on her big musical comeback last year when she performed several songs at the 2011 iHeartRadio Music Festival.

"It's going to be this amazing concert ... to launch the new iHeartRadio, where you can kind of customize your own radio stations," Lopez said after her performance was announced. "So, it's pretty exciting. I'm glad to be doing it."

Lopez did an amazing job mixing her dance moves with live singing. Check out her performance of "Let's Get Loud."

Lady Gaga

Before last year's festival, Lady Gaga teased that she might play a long set.

"I feel like I'm the most alive when I'm on stage ... I know I'm only supposed to play for 45 minutes, but because I'm the last act, I might perform longer," she told Seacrest.

She did put her heart and soul into the performance. Case in point? Her theatrical rendition of "Bad Romance."

Chris Martin and company brought the audience to their feet when Coldplay performed a hit-filled set at the 2011 iHeartRadio Music Festival. Our favorite performance of the show — hands down —  was their heart-tugging "Fix You."

Just because you don't have tickets, doesn't mean you have to miss out on all the fun!
