Even if you don't know her by name, you probably have her in your CD collection. She has provided backing vocals for a who's who of performers ranging from Etta James and Delbert McClinton to Trisha Yearwood and Wynonna to Kristen Chenoweth and Bruce Cockburn. She was the first and only female vocal choice of super producer Don Was when he started his own project The New Maroons with Benmont Tench (Tom Petty & the Heartbreakers), Ringo Starr and Mark Goldenberg. And Jonell Mosser is just getting started.
