If you look up digipak on wikipedia, you'll see it contains four or six frames. There are loads of examples on play.com and several linked to this the exam board's advice blog below which gives examples of excellent candidate blogs. This one contains a digipak which is very well constructed and comprises six panes. Scroll down to find it.

For your G324 project you are not simply creating a music video, but in reality you are creating:
"A promotion package for the release of an album, to include a music promo video, together
with two of the following three options:
a website homepage for the band;
a digipak for the album’s release;
a magazine advertisement for the digipak."
So in reality you are creating a new band, and promoting a new fictitious album from them. (Only you will be 'borrowing' a real song to use for the video part) Your blog and your research should reflect this. You will need to research bands and artists as a whole and see;
How they promote themselves across multiple platforms (video / website / artwork)
If and how they create consistent theme through image, style, design, colour, narrative, tone, etc.
How these various elements come together to promote a single media text (in this case an album)
As an example, have a look at this from CHVRCHES. A pop/electronic band from Glasgow who are about to release a new album called " Every Open Eye"

What you need to do, is put an analysis of more than one artist on your blog, who is currently or has recently promoted a new album. You should include examples of the media texts listed in the brief (Videos, website, artwork, magazine adverts). What you need to do, that I have not done, is to analyse and evaluate the images and examples you are adding to your blog to answer the questions I put at the top of this post.
