Nine unique acts take the main stage on Friday, Saturday and Sunday, spanning cover bands and soul-searing duos to “Industrial Country.” There’s sure to be a sound for everyone.

Friday, Aug. 12

Originally conceived as a hip-hop group, Eclectic Approach, playing from 6 to 7:30 p.m. Friday, has expanded its musical horizons and fully embraced the name.

Brining the blues, funk and rock at 6 p.m., Kent-area-based Sub Motive emerged from the Seattle music scene. After appearing in the first “Sound Off” band competition at the Experience Music Project in February of 2002, their popularity with audiences across the Northwest expanded into teen clubs as well as nationally renowned music festivals.

Two years ago, no one had defined “Industrial Country.” But today, nationally touring Chance McKenny & Crosswire are working to make it a household phrase. Playing at 8 p.m., the group blends country music with ‘90s rock, ‘60s motown and heavy metal influences. It’s a different combination, but true to country’s blended origins. After all, who knew the country music of your parents or grandparents’ generations would transform into the all-encompassing genre it is today? Learn more about the band at www.chancemckinney.com/.

Sunday, Aug. 14

Appearing from noon to 1:30 p.m., Correo Aereo (Air Mail, in Spanish), plays traditional and original music of Latin America; primarily of Venezuela, Mexico and Argentina. Together, Abel Rocha and Madeleine Sosin play instruments including latin American harp, guitar, violin, maracas, quatro, bombo and jarana. They are life partners, “artistically married,” Sosin says.

Their music “can be gorgeous and joyful, it can be haunting,” she says. “If a person opens themselves to receiving the music, they’re going to be deeply moved, but not just in one way.”

Music is the universal language, and it doesn’t matter if you understand the lyrics.

“Music will enter you and permeate you, lift you up,” Sosin said. “That is the healing power of music. It connects us all together.”

If you’re a fan of The Cars, or just of the 1980s in general, All Mixed Up may be just what you needed. The group formed several years ago when several bandmembers wanted to perform The Cars’ eponymous first album.

Playing at 2 p.m. at the main stage, the group performs a special tribute to The Cars, as well as a selection of hits from the 80s.

Band leader Jim Freeman admits that he missed the impact of the era’s music when the ‘80s were young.

At the time, he was into world music, blues and jazz. But today, he recognizes the energy of the era, and how it moves people in their 40s and 50s, as well as 20-somethings who probably never heard “Drive” on the radio.

If All Mixed Up do not enjoy playing these songs, they don’t get played. They don’t impersonate Okasec and company, but do favor black-and-white checked ties and Vans as a uniform of sorts.

“It’s been a blast playing this music,” Freeman said.
