On Mister Mellow, Greene draws from the experimental collage techniques of musique concrète and plunderphonics artists such as The Residents. Combining styles as diverse as free jazz, house, hip-hop and psych together with interlude-esque voiceover samples, often pulled from anonymous YouTube vlogs, he creates a busy, chaotic, and caricaturish mix that mirrors the claustrophobic, hyper-stimulated psyche so familiar to young adults.
