Sara Bareilles is an accomplished singer, songwriter, and author. She’s been nominated for six Grammy Awards and is also a New York Times bestselling author for her memoir Sounds Like Me. Her piano-rock sound has her listed as one of the best musicians on many pop lists, but in 2015, she turned to Broadway to adapt Adrienne Shelly’s cult film Waitress into a musical. Her #whatsinside series on Instagram gave fans a sneak peek at the music from Waitress, and to answer fan questions, she posted images of handwritten questions with her answers in captions.
