Prior to the 2018 midterm elections, Marc Erelli penned a song about America's problem with guns. With help from Lori McKenna, Roseanne Cash, Sheryl Crow, Josh Ritter and Anais Mitchell, Erelli released "By Degrees," with all proceeds benefitting Gabby Giffords' gun violence prevention organization. This morning, we dedicated two sets of music to this issue, with tracks also from Josh O'Keefe, Cheryl Wheeler, Steve Earle and Warren Zevon.
