This document discusses the coherence and effectiveness of promotional materials created for a metal/hard rock band called AlterVertigo, including a music video, digipak, and magazine advertisement. Feedback indicates the video and instruments fit the genre well but the advertisement could have been more colorful. Settings were kept consistent between elements to maintain a coherent style, though the drummer's smiling in the video was seen as inconsistent with the genre. Ways to improve coherence and address the feedback are discussed.
