NME, a multimedia company that spans magazines and music events. The company produce an incredibly successful magazine, but also host high profile music events globally. considering that they host both events and magazines, they need a recognisable art style to carry over all their media.
The NME logo and art style is successful for a reason. the company is centred around indie styles, but produce content on all different kinds of music. as such, their house style needs to be reflective of that.
The bold red and white NME logo is instantly recognisable.
notice how it holds the largest place of any graphic on both the magazine and the festival poster. red is an attractive colour, often associated with Indie rock in terms of music.
The magazine keeps up this theme, all text is either red or white, but most of it is red. A lot of elements of the magazine cover are red, this make it attractive and stand out.
The poster goes for a different approach, as it is a festival for multiple genres of music, where as the magazine is more focused on indie rock and an art style to accompany that.
It keeps the bold red NME logo, but ditches red as a general colour scheme. So the logo is still attractive, but the colour scheme has changed to accompany a wider target audience. Red is tailored for a specific group, people who like exciting, faster paced things.
Blue is a smart choice, as it is often viewed as a neutral colour. It is not associated with any particular kind of music and is generally attractive, making the poster more appealing to a wider audience of people, hopefully gaining a larger crowd for the event.

However, the poster is not so different that it becomes unrecognisable as an NME product. the poster uses the same style of text and the general layout is similar to the magazine cover. This helps people recognise the brand, fans of the magazine will recognise the style and vice versa.
Overall, the shift in art style allows NME to diversify their media output for a wider audience. Being a large company, they need to make profit on these events. Their magazine is targeted at a more select audience, but the poster is clearly designed to be more accessible to a wider audience. it is this shift that makes it a successful brand as it allows them to target more a wide audience
Doc Fest is another example of a successful brand. Doc fest is a massive festival in which people present their Documentaries to an audience in the hopes that someone will pick them up on their works.
They use a consistent style of bold, blocky text with a sort of graffiti style to it. the logo is always in the same position across each piece of media too, the top left corner.
Both the poster and the ticket are very similar in terms of layout too.
The poster is very simple. a logo and text are all that comprise it, with a distinctive pink background to accompany it. this simple, bold design makes it stand out with it's large text and logo
The ticket on the other hand uses black as it's primary colour to make it discernible from the flyers and posters. otherwise, it remains largely unchanged. Text has been re organised to fit on a ticket, and a ticket number has been added beneath the logo, but it is still recognisable as part of the same festival considering it's similarities to the poster.
The Doc fest is an example of a successful event as it's style is simple and very effective. It's style remains largely unchanged across the board, with bold, bright, eye catching colours matched with large, stylised text to convey all necessary information while keeping it simple.
