The document discusses the effectiveness of combining a band's main product (their album) with ancillary texts like a digipak, music video, and advert. There are links created between the products through using consistent props, locations, imagery and logos. However, some links could be stronger by adjusting small design details. Overall, the combination of products is deemed effective as they create synergy and recognition between the pieces. But the document suggests there is still room for improvement to make the links and synergy even stronger.
