These days, Las Vegas is a haven for music festivals, with the likes of Life is Beautiful, Electric Daisy Carnival and Route 91 Harvest bringing huge crowds of music fans to town. By now, the iHeartRadio Music Festival is the veteran among them, having launched in 2011, and returning now for its fourth year, Sept. 19-20. While other festivals generally focus on one particular musical genre, the iHeartRadio Music Festival embraces a range of styles, offering up popular artists in pop, hip-hop, country, alternative, rock and dance music, making it a perfect representation of the variety of radio stations that make up the iHeartRadio brand.

Performers at this year’s festival range from legacy acts like hard rock lifers Mötley Crüe and alt-rock veterans Weezer to newcomers like pop starlet Ariana Grande and rapper Iggy Azalea (not to mention pop-rockers Before You Exit, the festival’s designated “rising star” act). Stars like Taylor Swift, 50 Cent, Ed Sheeran, Lorde and Eric Church are also on the bill, all set to perform their biggest hits for the eager crowd. For people who can’t score a highly prized ticket to the festival itself, there’s also the iHeartRadio Music Festival Village across the street, featuring performances from Iggy Azalea, plus country singer Kacey Musgraves, rapper Childish Gambino, rockers The Pretty Reckless and more.

MGM Grand, 7 p.m. Sept. 19-20, starting at $160.50 plus tax and fee. 800.745.3000 Ticketmaster
