It’s been three months since Chris Cornell died, a period of time that’s been marked with a number of tributes to the Soundgarden and Audioslave musician, from his family, from his hometown of Seattle, and from a great many of his friends and fellow artists. Now, Cornell’s widow, Vicky Cornell, is inviting the rest of us to chime in with their messages of tribute, too, posting on Twitter today that she’d like Cornell’s many fans to submit their favorite memories of his music and his life.
