John Mark Nelson is a Los Angeles based producer, songwriter, and artist. After being anointed a "wunderkind" by NPR in his teens, dropped by his label in a dizzyingly short timespan, and taking an opportunity to work with Grammy award winning songwriter Dan Wilson in Los Angeles, Nelson finds himself creatively reinvigorated. As a writer and producer, he has co-written/produced recent releases including Devon Cole’s “W.I.T.C.H.” (garnering millions of streams across platforms after going viral on TikTok), Suki Waterhouse’s “Nostalgia,” “sunrise mtn” by Jenny Owen Youngs (he is also featured as an artist), “Movie Star” by Trousdale, “Who Am I Now” by alayna (Nettwerk), “A Little Love” by Julia Pratt and Mt. Joy, and more. He attributes much of his growth in both songwriting and production to his experience at Wilson’s studio working with new artists every day, including the likes of Mitski, Leon Bridges, and Taylor Swift, for whom Nelson served as an engineer on tracks for the re-recorded Red LP. As an artist, he has racked up millions of streams and a sync placement in Devil in Ohio.
