She considers Ella a major influence and uses her singing as a teaching tool for her voice students. Tuesday is Ella's 100th birthday . To celebrate, Matassa sat down with KNKX to talk about her life with Ella. Matassa and her band will be performing a birthday tribute to Ella Tuesday night at Bake's Place in Bellevue.
