My uncle Pete sent Sam and I one of his Rock Family Tree posters.
We love it!
Pete founded the music magazine ZigZag in 1969 and created the first ever Rock Family Tree for its 21st issue. They subsequently appeared in Sounds, NME, Melody Maker and Rolling Stone, on album sleeves and CD inserts. BBC Television broadcast two series of Rock Family Trees.
Each rock family tree was hand drawn and accuarately plots the careers of 100's of rock bands through the ages from Frank Zappa to Fleetwood Mac. He's covered the whole rock spectrum from punk to progressive.
Graphically they are works of arts.
Next up is Nirvana and Elton John.
Check out his blog.
He has so many cool stories from the 70's.
