Some of the biggest voices in music are also Hillary Clinton supporters, and they're using their pipes to champion the Democratic frontrunner.
Clinton will also take the stage, though she won’t be singing backup for Martin’s "Livin’ La Vida Loca." The presidential hopeful will use her voice to bring attention to women's equality, climate change and immigration reform, issues that have been important to Clinton throughout her 2016 campaign.
The star-studded concert will take place at the Greek Theatre in Los Angeles on the night before the California primary, a critical contest in determining whether she or competitor Bernie Sanders will win the Democratic nomination.
The Hillary Victory Fund held a similar “She’s With Us” concert in New York Radio City Music Hall back in March, with performances from Katy Perry, Elton John and Andra Day.
