Cherri Bomb was a hard rock band formed in 2008, while its members were still in middle school. The band was originally an all-female hard rock group, consisting of Julia Pierce (lead vocals, lead guitar), Miranda Miller (rhythm guitar, keyboards, backing vocals), Rena Lovelis (bass guitar, backing vocals), and Nia Lovelis (drums, percussion, backing vocals). In 2013, Pierce left the band and was later replaced by Casey Moreta. In 2015, the group changed their name to Hey Violet and drastically altered their sound to pop.
The name Cherri Bomb originated from the book Cherry Bomb – The Ultimate Guide to Becoming a Better Flirt, a Tougher Chick, and a Hotter Girlfriend, and to Living Life Like a Rock Star by Carrie Borzillo. On June 14, 2011, they signed to Hollywood Records, and on October 18, 2011, they released their debut EP, Stark. The band released their debut studio album, This Is the End of Control, on May 15, 2012, which charted on Billboard's Top Hard Rock Albums at number 24 and Top Heatseekers at number 11. They appeared on the Warped Tour in July–August 2012. In August 2012, they toured with the Welsh rock band Lostprophets.
