Gunakadeit, now Natula, celebrates 30th at Fernwood.

Less than a week ago, Natasha Kozaily made the transition from benevolent sea monster to inquisitive child. It represents a transformation of her music’s outlook and direction.

For years, Kozaily’s bright indie-pop sound came infused with world music, used the name Gunakadeit, in honor of a sea monster who saves a village from starvation in aboriginal Alaskan folklore.

On Oct. 17, she issued a statement on Facebook explaining the reasons she is ditching the scales and tail.

“[Gunakadeit] served as a symbol of all that is good in the world, even among the wickedness and suffering… but the story of Gunakadeit comes from the indigenous Tlingit people of Alaska, and it belongs to them, not me,” she writes.

She debuts Saturday at Fernwood in Big Sur as Natula, which translates as “little girl” in Latin. It is a nod to the hopeful and honest outlook she wishes to cultivate as she navigates existential terrain woven of cultural identity.

Kozaily’s Caymanian mother and Lebanese father raised her in the Cayman Islands. She absorbed their cultures, as well as those of expats on the islands.

She calls her all-embracing musical aesthetic “third-culture pop.”

“Third-culture kids come from multi-cultural upbringings,” she says. “They speak multiple languages and move fluidly through different cultures. But they sometimes struggle with identity.”

She studied musicology and world music, deepening her blend of international sounds in pop context, well within reach for fans of indie chanteuses like St. Vincent and Regina Spektor.

The flirtatious “Afterschool Special” breathes coy lyrics about an affair between an older man and a teenage girl.

“You’re the elder/ I know you’re older/and that’s the appeal… teach me I want to learn,” she sings.

The song “South” is Kozaily’s response to feeling constrained by societal pressures. In the video, Kozaily follows a pale, gaunt woman who puts on lipsticks and wanders around an impressive home, dead-eyed, spilling milk, stripping off layers of clothes, and finally falling backward into a pool in her underwear and high heels. Kozaily is invisible to the waif. Keyboard notes decay like rotting fruit.

“I’m her voice,” Kozaily says about her role. “I’m telling her to let go of a life that weighs on her and makes her sad.”

To celebrate her 30th birthday Friday, Kozaily embarks on a tour of 30 cities where she will play 30 house concerts in an effort to raise $30,000 for the Syrian refugee crisis. So far London, Paris, Istanbul and Beirut are on the circuit.
