Lil zMac released AUX: The EP on Halloween 2024, just 10 days after dropping Olympus. The tracklist includes: INTRO TO AUX, AGGRESSIVE, COFFIN, Stop, every night, and ruok. The stylized capitalization reflects the EP’s structure—starting with high-energy rage/trap tracks to energize listeners, then transitioning into softer, more introspective hip hop, with a boom bap interlude (Stop) bridging the two moods.
Lyrically, the EP explores themes of sickness and conflict in the first half, followed by a shift toward vulnerability and love in the closing tracks. AUX also introduced the recurring coffin motif into Lil zMac's aesthetic—used as a symbol of self, often appearing in his usernames and coffin emojis across platforms.
