Old School Freight Train, a bluegrass band with four members hailing from Charlottesville, Va., has earned the nickname of being a “newgrass” band because of the band’s twist on old bluegrass sounds.

The band — made up of mandolin player Pete Frostic, Jesse Harper, guitar and vocals, Darrell Muller, bass and vocals, and fiddler Nate Leath — will play tonight at Stewart Theatre at 8 p.m. The concert is free for students, $20 to $24 for the general public and $15 to $19 for faculty and staff, with a big emphasis on it being free for students.

“It was free,” Ryan Springer, a freshman in mechanical engineering, said. “So, I checked their website, and I liked what I heard.”

Students can get tickets from Ticket Central with a student ID, but Mark Tulbert, associate director of Stewart Theater, said they better get them while they can because it’s likely they will sell out quickly.

There are quite a few Old School Freight Train fans on campus, including Heather Ridlon, a sophomore in biological sciences, who has been listening to its music for more than a year.

“I’m not going to be able to [go to the concert], but they are really great,” Ridlon said. “They put a new vibe on blue grass music.”

This music took years to develop, according to Pete Frostic, the band’s mandolin player.

“We have been doing it long enough to where we have got our own sound now,” Frostic said.

The band has been playing together for six years now. While they have played at college campuses before, Frostic said they are anticipating playing at N.C. State because they don’t get to play the campuses enough.

“It’s something we like to do,” he said. “We are always well-received and people dance and have a good time.”

This is just what he expects tonight.

“[Audience members] are going to have fun for sure,” he said. “We are always cracking jokes, but not like lame made-up humor — they can see some high level of musicianship and hopefully good songs.”
