Shaver may not be a household name, but he wrote and recorded many songs that are considered classics of the 1970s and '80s, including "Honky Tonk Heroes," "Old Five and Dimers Like Me," "I'm Just an Old Chunk of Coal" and "I Been to Georgia on a Fast Train." He's probably best known, though, as the writer behind nine of the ten songs on Waylon Jennings' landmark album Honky Tonk Heroes. Released in 1973, that collection of scrappy, stripped-down recordings signaled a change the sound and approach to making music in Nashville � and the start of what became known as country music's 'outlaw' era.

Long in the Tooth is Shaver's first album since 2008′s Everybody's Brother. And Shaver isn't shy about sharing his thoughts on his latest achievement. "This is the best album I've ever done," he said in a press release. "It's just dangerously good. I expect it to change things and turn things around the way Honky Tonk Heroes did."

Rolling Stone premiered a new song from the album, "Hard to Be an Outlaw." The western-flavored song is a duet with Willie Nelson, and it takes a few unveiled potshots at the current state of country music.

"Some superstars nowadays get too far off the ground," Shaver sings in the song, "singing about the backroads they never have been down."
