The first of the Summerfest 2025 Headliners is none other than Def Leppard. The band celebrates their 49th year in the rock scene on their current tour. Rick Savage, Joe Elliott, Rick Allen, Phil Collen, and Vivian Campbell made their mark in the early 1980s heavy metal scene in England. How did the band break out and become worldwide rockers? They listened to the advice of producer Mutt Lange and produced their breakout album titled High ‘n’ Dry. Pyromania was the album that followed, and it just proved that the High ‘n’ Dry was not a fluke. Their 1987 album, titled Hystaria, was a massive hit for the band. The 22-time platinum album was the last album produced by Lange. Def Leppard would go on to produce a total of 12 albums, with their last effort titled Diamond Star Halos. Def Leppard performs on June 19.
Hozier performs at Summerfest on June 20. Hozier’s self-titled album hit number two on the US charts. The album went platinum in Ireland, Germany, England, New Zealand, the Netherlands, and the United States. Hozier started writing music in 2008, but he waited until 2014 to go solo. His song, Take Me to Church was nominated for a Grammy. His 2025 tour starts in Bogota, Colombia, on May 21. He’ll wrap up that tour on October 14 in Mexico City.
Lainey Wilson will perform at Summerfest on June 26. Wilson hit it big with her song “Things a Man Oughta Know”. That hit came in 2020 after signing with BBR Music Group. Her album, titled Bell Bottom Country, earned Wilson a Grammy nomination for Best Country Album. Wilson can also be found on the show Yellowstone. Wilson is thrilled to be a Summerfest 2025 headliner after years of hard work in the music business.
Benson Boone Hits Summerfest 2025 Stage
On July 3, Benson Boone will hit the Am-Fam Summerfest stage. Boone made an impression with the single “Ghost Town” in 2021. He went through the talent show route to try to make a splash online. He left American Idol after making it a few rounds and decided that TikTok was a better channel for auditioning to various record labels and talent scouts. That effort paid off when he was discovered by Night Street Records owner Dan Reynolds. Evan Blair and Jackson LaFrantz co-wrote Benson’s biggest hit song, “Beautiful Things.” Boone has just one album to his name, but with good songwriters producing hits that he can sing, he’s got a shot at making a few more songs top the charts before he ages out of the teen fan base he’s known to attract.
The last of the Summerfest 2025 headliners will be The Lumineers on July 5. It all started in 2005 when Wesley Schultz and Jeremiah Fraites started hammering out cover songs and plying their trade in the New York City area. Like so many other bands, they started with cover songs. Eventually, the duo wrote their own songs and then moved out of New York. 2010 is truly when The Lumineers found their footing and got signed to Onto Entertainment for proper management. Their 2011 song “Ho Hey” generated a big buzz, and The Lumineers were courted by various record labels. The band made the wise choice to keep some of their creative control and released their first full-length album on an independent label. That isn’t to say that the band wasn’t supported by huge labels. They were licensed out to Decca and Dine Alone records, just to name two huge labels.
The Lumineers produced five albums in the past 12 years and globetrotted on four world tours that spanned seven years in total. For this tour, the band is supporting the release of their album titled “Automatic.”
