Here is a large and very detailed Rock Family tree graphic drawn by Pete Frame. This one has a personal connection for me. It describes the hugely energising creative outburst of bands that happened in Liverpool UK in the early 1980's and centred around the famous Erics club, which opened on October 1, 1976 in a building basement on Mathew Street opposite The Cavern Club where The Beatles had played.
Pete Frame had this to say in his graphic;
"For the second time in twenty years, Liverpool is the most exciting city in the whole rock world. In my few days there, I became so intoxicated with the place that I collected far too much information for one family tree - so what you see here is the basic framework for a wall-size effort."
I lived locally and went to Erics and other clubs around often enough to have seen or heard of most of the bands or people on this graphic.
Here is a zoomed in piece of the graphic linking the bands Echo & the Bunnymen and the Teardrop Explodes with Bill Drummond (who famously set up the KLF and burned a million pounds as a piece of conceptual art). In late 1979 I saw Echo and the Bunnymen (complete with Echo the drum machine) support The Teardrop Explodes at Chester art centre.
