"He was very supportive," Jennings said. "I was in love with music as much as he was, and he liked that."
Shooter Jennings acted as his father, Waylon, in 2005's Walk the Line-- a movie based on the late Johnny Cash. He auditioned for the part and met up with the director, but he said he thinks he got the role mainly because of his voice.
"I for sure could not act," Jennings said. "It was very surreal. I'm not a movie star."
Grote said she thinks that movie's release helped to increase audience interest in Jennings because he portrayed his father, whom the audience was probably familiar with.
"I can't say for sure if it's helped record or ticket sales, but a lot of his tour press has made comments regarding his appearance in the film, so I would definitely say it's helped in terms of his popularity," Grote said.
Jennings said the movie made people aware that he exists and brought up his record sales.
"I got my first platinum record because of that," he said.
Grote said Jennings wants to make music that continues to push the boundaries.
"Shooter has always said he wanted to make country more interesting and on his own terms, and he does just that," Grote said.
Jennings released his third album in April. He said that although his three albums don't share a common thread, the most recent one is part of the trilogy with the first two, making one big piece.
"It's a lot different, just like the newest one is different from the first one," he said. "I don't want to say it's the best because they all have a different vibe to them."
The Deadstring Brothers, who will also be performing tomorrow, perform a style of music similar to that of Jennings. Their music is a combination of country, rock and blues.
Concert promoter Ted Swanson said for tomorrow's performance there is just as much interest for The Deadstring Brothers as there is for Shooter Jennings. He also said the band's music backs up the hype.
The Deadstring Brothers met Jennings and his band on a tour this summer, although Jennings said he had heard their music earlier on satellite radio.
"I'm excited to see their show every night," Jennings said.
