Sun Records, which premiered last month and airs Thursday at 9 p.m. ET/PT, tells the untold story of the Memphis record label where Elvis Presley and Johnny Cash got their start.
"Everybody knows the icons -- the Jerry Lee Lewis, the Elvis, the Johnny Cash -- but to now see it kind of through Sam's eyes [is new,]" Murray revealed to ET last month. "He's the man that found all of this and that started rock-n-roll and he was kind of the man behind the curtain that no one knows. It's going to be an incredibly exciting time. I'm excited to see how people respond."
