Shania Twain is mouring the death of Allison Cornell - a violinist, violist, synth player and multi-instrumentalist who has been part of her touring band for years. Shania shared a couple of videos of Alison's contributions to her live show on social media. "Allison Cornell was such a talented and wonderful person," she wrote on her post. "It was a privilege, as an artist to have her on stage with me through a lot of my touring career. Feeling very sad. Alison's memory will live on but sadly another beautiful human being has gone too soon. Rest in Peace." No cause of death was revealed.
