Conclusion:

• It is conventional to have an easy to read font – it can be any kind of font (one that connotes relaxtion, or one that is formal) as long as it is big, bold and readable.
• There is always a picture, be it dancers or the band themselves.
• Colour palettes are very minimal – they often have two or three colours. This is probably because the two tone colour scheme is conventional to the genre itself.
• Two of the three posters I analysed have song names on, this suggests that this feature is likely to be conventional.
• Formats that the album are on appear on all the posters so this feature is highly conventional.
• The albums generally have a tagline, or some kind of review. We will put this on our poster because it is conventional, and should sway people to buy our product.
• A record label will usually appear on the poster.
• There is no set star image. It is really up to the band/photographer to decide how they will portray themselves.
• It is rare for a poster to have the price on, this is an optional feature.
