"Lavish" is a soulful yet rhythmic Amapiano standard comprised of sultry instrumentation and saxophone phrasing inspired by Jay-Z's hit song "Show me what you got." Its initial impression offers a feeling of refinement and elegance without appearing pretentious. Then the song slowly reveals a pleasant transition into measures of hard-hitting log drums, entrancing synths, and unapologetic percussion. And as the track nears completion, it smoothly descends listeners into a grounded and refreshed state.
