Marshall Hamburger

is an Australian retro pop-groove artist, pianist, and vocalist known for his soulful voice, vintage flair, and magnetic stage presence. Winner of Australian Idol 2025, Marshall rose rapidly to national prominence, performing alongside Australia’s top session musicians and cementing his place as one of the countries freshest musical voices.

Influenced by greats such as Michael McDonald, Billy Joel, Clyde Lawrence, and Elton John, Marshall brings a blend of throwback soul and modern pop grooves to his performances. Whether behind a grand piano or layering synth textures on stage, his music channels nostalgia while staying refreshingly current.

At heart, Marshall is a storyteller - with a keyboard and a grin. His deep respect for the piano as an instrument and the craft of songwriting shows in every note he plays. Offstage, he’s just as likely to crack a dad joke as he is to launch into a spontaneous jam session, but when the lights come on, he’s all in.
