Fans of the CW's "One Tree Hill" are in for a double treat this fall. With the drama's seventh season currently filming, its musical voice, Mia Catalano, is both on the show and on the road in the flesh as Kate Voegele, who plays the singer-songwriter, tours to promote her sophomore album, "A Fine Mess."

"They go hand in hand; it's not like it's different entities," the 22-year-old Voegele tells Billboard.com about balancing the acting and music gigs. "(The CW) does such a good job of promoting the musical thing I'm doing. What's been incredible about the show is they really have been so accommodating of the fact I'm a musician first, and they give me time off if there's a tour like this or I have something else to do. Those guys are really the reason I'm able to do both and not go crazy."

Voegele kicks off her latest tour on Wednesday (Oct. 7) in her home town of Cleveland. "A Fine Mess" came out in May and debuted at No. 10 on the Billboard 200. She and her band have been preparing for the 30-show trek, which wraps up Nov. 15 in Chicago, and Voegele says she's looking forward to having a larger body of work this time. combining the "A Fine Mess" songs with selections from her 2007 debut "Don't Look Away" and also throwing in a few covers.

"I've always had a bazillion songs in my archive, but I want to play people stuff they know," Voegele explains. "Now that I have two albums' worth of material, that gives me freedom to compose a set that's more well-balanced and build a show rather than just a recital of some songs. The set's going to have highs and lows. More than anything I want to get up there and hang out with the audience, make everybody feel like it's fun and they're involved and are just, like, friends hanging out in somebody's living room. I went to see Carole King on her Living Room Tour, and that's the kind of feeling I'm aiming for."

Voegele will also be doing a bit of charity work with the tour. Her sponsor, the online University of Phoenix -- through which Voegele is pursuing a Bachelor of Science in psychology -- is contributing up to $50,000 to the Council of Greater City Schools, which serves 66 large city school districts around the country. The school will donate $1 for every one of Voegele's fans that texts a certain number, pledging support for public education.

"It's something cool that promotes a good message," Voegele says. "It's awesome when you have a platform like this and can be in front of a bunch of people and promote a message other than, 'Hey, buy my CD! Watch my TV show!' It's something that will make the people in the audience feel like they're part of something."
