The document summarizes four experiments conducted by Harry Taylor to develop techniques for a music poster and album cover. In the first experiment, Taylor created a poster for a summer tour using techniques like cutting out the artist, adding a stroke, and experimenting with brush fonts. In the second experiment, Taylor created a CD cover using graffiti text over a scenic image. The third experiment created a glitch effect using layers, blending modes, and overlays. The fourth experiment was an animation replicating the glitch effect over multiple frames. Taylor reflected on including elements from the experiments, like graffiti and glitch effects, in a final product.
