In 2004, singer-songwriter Mary Gauthier introduced McKenna's album "Bittertown" to her Nashville friends. Upon hearing it, Faith Hill stalled her completed 2005 record "Fireflies" to replace tracks with covers of McKenna's songs. Hill and husband Tim McGraw became McKenna's champions and asked her to tour with them in 2006. Hill took McKenna to perform with her on the "Oprah Winfrey Show". McGraw helped bring McKenna to Warner Bros. Nashville in 2007 and produced her album "Unglamorous." Following the lackluster sales, she parted ways with Warner Bros. She then signed with Universal Music Group Publishing in 2009 and independently released her next album "Lorraine" in 2011.
