If you are looking for the freshest, never-before-heard Melody Walker songs, you can find those on Patreon - a micro-patronage platform for artists and musicians. For $1 USD per month you get access to Melody's patron-only stream where she posts at least one brand new original song each month. It's like a subscription to the creative process, and you'll hear new songs long before they are recorded or performed live.
