It is not uncommon for Julianna Zachariou to hear something like “I am a giant music critic and am very hard to convince, and I just love what you do.” It’s kind of her M.O. — she can show up to any room and make strangers collect themselves into a focused and eager audience. Though she is an accomplished songwriter, multi-instrumentalist, and music producer, Julianna boasts that her biggest gift is simply her ability to understand and connect with others. Julianna Zachariou’s newest record, “Hero of Your Heart” is joyfully disarming and now streaming wherever you listen to music. She is based in San Diego with her dog, Goose, and her partner Becka.
