Star Sign: Aquarius
Nazuna's a bit of a complicated figure in music—he was once recognized as a guitar prodigy, the kind of talent people expected big things from. Then focal dystonia derailed that path, and instead of chasing comebacks or medical miracles, he shifted gears entirely. These days he runs a small studio, which is where you'll find him doing what he actually enjoys.
Despite his credentials, he's turned down offers to join various bands over the years. Currently, he plays keyboard for Bluebird, which is probably his most public-facing role at the moment.
