A gifted songwriter and a versatile pianist with no formal training, Sara Bareilles burst onto the pop scene in the early 2000s with a dynamic vocal range that earned her early comparisons to Fiona Apple, Regina Spektor, and Ingrid Michaelson. Her breakthrough sophomore effort, 2007's Little Voice, went platinum, while follow-up Kaleidoscope Heart topped the charts in 2010. In addition to her pop pursuits, Bareilles also delved into the world of theater, writing the music for the 2015 Tony-nominated stage production Waitress (she later starred in 2017/2018 engagements); starring in the 2018 Emmy- and Grammy-nominated Jesus Christ Superstar Live in Concert!; and contributing to pop reimaginings of tracks from Hamilton and The Greatest Showman.
