King Neptune was born of necessity.

The Long Beach-based singer-songwriter (formerly known as Ian Kenny from NGHBRS) says he realized he needed a name change when he started co-writing with other writers. “I wanted to have my own persona,” he says, adding that the name came from the jokey alter egos of NGHBRS, King Neptune and The Crustacean Army, which played jazz versions of the band’s songs. “I wanted to be able to take my own liberties and not be limited by genre. It was my chance to just use my voice in a lot of different capacities.”

The new persona has paid off. King Neptune has been extremely prolific in the past two years, writing more than 100 songs in all sorts of genres. And after offering a few singles like the promising “Black Hole,” he is planning to release his first EP, “A Place to Rest My Head” (King Neptune), on Oct. 14, which focuses more on his indie-rock interests.

“I love Weezer and the Pixies, but my writing style is different from those bands,” he says. “I’m more simple, more about telling stories. Johnny Cash is one of my favorite writers. . . . I want to create a new experience for people.”

King Neptune plays The Footlight, 465 Seneca Ave., Ridgewood, on Oct. 16.
