Shooter Jennings' father, Waylon Jennings, passed away in 2002, at the age of 64. The country music icon had released more than 50 albums of material, but his son says there's still more to be heard, and he's ready to share it with the world.

The new music, which was brought to the younger Jennings by a small boutique country label, is from a session his father recorded in 1970 at Music City Records, the studio run by Elvis Presley's guitarist, Scotty Moore.

"When I heard this stuff, they said it was my dad's band, and that didn't make any sense because it didn't sound like Richie Abright on drums," Shooter Jennings tells Rolling Stone Country. "It's a very interesting period, because it was the only period during that era that my dad did not have Richie playing. Also, there was an organ. My dad had a guy playing keys with him all these years, but he rarely had an organ player. It was a strange thing."

The 35-year-old says that he will release "a lot of Waylon stuff over the next year," even though he admits much of the recording remains a mystery.

"My suspicion was they had radio stations that broadcast to the soldiers, but instead of having to license or do whatever with record label recordings, I think they'd have artists come in with their bands and cut 12 or 15 songs, and that's what they would play," Jennings explains. "I wish I had more information because it's not normal for me to run across something like this. This is the first time I've heard them."

Jennings released a vinyl edition of some of his father's music, 'Louisiana Man, Kentucky Woman,' on Nov. 28, for Record Store Day's Black Friday initiative. Purchase the limited-edition album here.
