Which band known for the song "Radioactive" released the hit "Warriors" in 2014?

The band known for “Radioactive” that released “Warriors” in 2014 is Imagine Dragons.

“Warriors” was created for the 2014 League of Legends World Championship and was officially released as a single on September 18, 2014. Its dramatic, arena-sized sound and lyrics about rising from hardship made it a natural anthem for competitive gaming, where teams battle through qualifying rounds to reach the world final.

The song was written by Imagine Dragons with Josh Mosser and producer Alex da Kid. It later appeared on the deluxe edition of the band’s second studio album, Smoke + Mirrors, released in 2015. This sometimes leads listeners to think it was originally an album track rather than a game collaboration.

Imagine Dragons had already become internationally famous through “Radioactive,” a breakthrough single from their 2012 debut album, Night Visions. “Warriors” began a long-running tradition of League of Legends World Championship anthems, with a new major song associated with the tournament in later years.
