Shortly after her death, the "New York Times" stated that Reider was "a singer-songwriter with a huge following back home and a growing national fan base, who seemed on the cusp of much larger success when her life was destroyed by a rare tumor that ate into her jaw and face, stole her voice, left her blind in one eye and finally killed her (in July 2008) at the age of 30."
