In 2002, Schnabel painted the cover artwork for the Red Hot Chili Peppers' eighth studio album, By The Way. The woman featured on the cover of By the Way is Julian's daughter, Stella Schnabel, who was band member John Frusciante's then-girlfriend. Regarding the artwork, Frusciante noted: "My girlfriend's father offered to do the album art, so we sent him rough mixes of eight songs, and he just got the vibe of the album from that. He said that he wouldn't be offended if we didn't like it, but we loved what he did. He's also given us great covers for all the singles. He's a true Artist."
