Allman's seventh album, "Low Country Blues", was produced by T-Bone Burnett. Upon its release in January 2011, it represented Allman's highest-ever chart peak in the U.S., debuting at number five. He promoted the album heavily in Europe, until he had to cancel the rest of the trip due to an upper respiratory infection. This led to lung surgery later in 2011, and rehab in 2012 for addiction following his treatments. That year, Allman released his memoir, "My Cross to Bear", which was 30 years in the making. In 2014, a tribute concert was held celebrating his career; it was later released as "All My Friends: Celebrating the Songs & Voice of Gregg Allman".
