Cami Lundeen knows firsthand the meaning of a wild ride. Last June, the former island singer, her husband and children set off from Vashon trailing a tiny pop-up camper to launch Lundeen’s nationwide tour. After traversing the country, performing in a variety of venues and gathering unique experiences that inform her new songs, Lundeen will return to play a show at 8 p.m. Sunday at the Red Bike.

Lundeen’s musical career and the impetus for her recent tour were spurred by a life-changing diagnosis the singer received in 2010, just before her 30th birthday. A mother of four small children, Lundeen learned she has a rare, incurable and progressive liver disease. In a phone interview last week from her current home near Gainesville, Florida, Lundeen spoke in her signature husky voice about life, the tour and her family’s four-month adventure.

“We left with not a lot of expectation, but we knew it was a risk we needed to take. It was such an incredible experience to travel with our children and have random, spontaneous experiences with other families we met.”

First stop on the tour found the family at a horse camp in Goldendale, Washington, where Lundeen played for the young campers. A house party in Portland, Oregon, came next followed by a month-long sojourn down the coast of California, where Lundeen played in assorted venues and the family played on sunny beaches. After stops in Las Vegas and Colorado Springs, Lundeen sang— much to her delight — in Minneapolis’ iconic music club First Avenue. Lundeen had sent an introductory email to the nightclub, telling her story and including links to her music.

Like First Avenue, the Ronald McDonald House at the Mayo Clinic in Rochester, Minnesota., responded positively to Lundeen’s inquiry, satisfying a goal she had to perform at children’s hospitals. Before leaving Vashon, Lundeen explained her wish.

“Kids are so helpless. And my music is hopeful, encouraging. It tells them not to be afraid. And it’s something my kids can be part of.”

Lundeen said her children really loved the trip, only showing signs of fatigue as the family approached Florida, where Cami’s parents had relocated last year.

“We got used to having the trailer as our home,” Lundeen said, “and even now the kids will say they miss the road. But towards the end, everyone needed a break from the constant movement. Sometimes I had a show every single night. It was exhausting and amazing.”

Lundeen said she’s looking forward to returning to Vashon, a place she found difficult to leave and still misses. Her band will include some local musicians — Wesley Peterson, Jason Everett and from Seattle, Chris Brandt, plus other special guests. Vashon High School senior Kate Atwell will open the show.

Talking about her song-writing, Lundeen said her lyrics have multiple meanings — literally and figuratively. The title track to her second album, still in the works, is called “Wild Ride,” a reference to both her tour and life in general.

“It’s been hard but amazing, and I wouldn’t trade it — this wild ride I’ve been given,” Lundeen said. “We’re dealt traumatic things, and we can wallow in it or have teachable moments. Life is a wild ride, and we need to make the most of it.”
