Rudy Gutierrez is one of my favorite painters ever. I first came across his work in a picture book someone got for my son called "Papa and Me". I fell in love with the colors and energy he gives to a piece. Since then he's done countless picture books, album covers, and more. I believe he uses a mixture of media, oil, pastels, acrylic, etc. Follow him on Instagram or check out his website. Rudy is an Boricua from NYC i believe. I have told him how much I dig his work and I invite you to look him up.
RIP Roy Hargrove
