Whilst listening to indie music on Spotify, I came across an album cover I thought was aesthetically pleasing. I like the minimal design of Perry's cover and that it features pastel colour which is very conventional to the indie genre. The large artist name immediately stands out with its bold type also.
In terms of image, I would prefer a photo rather than a sketch as it clearly showcases the artist on their own, drawing attention to them as a commodity and sales point- the basis of music promotion material. I would utilise the same medium shot but perhaps with a more varied colour palette like in this image. I think I would have my artist looking away from the camera to create a disconnection and mystery common to indie artists.
