Leo Marsh

Leo is a multi-instrumentalist and former gigging musician who started Zantrixos because so much music advice is gatekept behind jargon and expensive gear. He writes about making music joyfully and cheaply, and he firmly believes that the worst song you finish teaches you more than the perfect one you never start.
