Rachel Cousins has always had a voice that could stop you in your tracks, but on her new album, “What Hasn’t Killed Me,” the St. John’s singer-songwriter turns that power inward. Working with Grammy-winning producer Greg Wells, Rachel steps away from pop perfection and into something raw and real — music about growing up, learning to ask for help, and finding beauty in the mess. She sits down with Tom Power to talk about baring her soul on this album and why the song “To Fail” means so much to her.
