The document discusses maintaining consistency across three promotional materials - a music video, magazine advertisement, and album digipack - for an indie rock artist. Specifically, it maintains consistency by [1] featuring the artist's face and style in all pieces, [2] using the same still from the video in the advertisement, and [3] using the same font throughout.
