W+S Charitable Foundation 

Curated by Stefani and Grammy Award-winning vocalist-songwriter, producer and revered guitarist Warren Haynes, the Christmas Jam is one of the most celebrated and longest-running live concerts in the U.S. Held each year in Haynes’ hometown of Asheville, NC, performing artists, volunteers and friends from all over the country come together to raise funds for the Asheville Area Habitat for Humanity. Proceeds from the Jam go toward constructing energy-efficient new houses (41 houses have been built so far) as well as purchasing and developing land for entire Habitat subdivisions. To date, the Jam has raised over 2.3 million dollars for the Asheville Area Habitat for Humanity.
