Looking at Rock Family Trees

I have been looking at the style of Rock Family Trees, which is a book originally created by Pete Frame. I have been looking at these because I have been thinking of making a poster that incorporates many artists of XL Recordings, and putting them in the style of a family tree or time line would work well for this.
 
Looking at the way these family trees are constructed, they are completely based are around text, and he uses different typographic styles to give the family trees n artistic style, rather than just being information on a page. They are set out in a way that the there is no leftover space left on the page, filling it up with his own stylised text and adding informative text to some of these family trees.
