It has been a busy month for singer-songwriter Erin Enderlin. The Conway native's new EP, "Barroom Mirrors," was released Oct. 15, which was also when she played the Grand Ole Opry on a bill with John Conlee, Bobby Osborne & Rocky Top X-Press and Connie Smith. And she was part of a star-studded lineup for the virtual Johnny Cash Heritage Festival that included Sheryl Crow, Darius Rucker, Chris Stapleton, Vince Gill, Margo Price, Keb' Mo' and others.
