A series of 16 stand-alone chapters revisit pop/rock history viewed through a prism of causality highlighting previously overlooked or obscure timeline moments crucial to the stories of the Sixties and Seventies greatest bands, singers, and songs playing out in the way they did. This fresh take on the Beatles, Stones, Kinks, Dylan, Bowie, and others provides substantial information when required, with occasional light humour as a new slant on events is revealed. "Chain Reaction" offers something different, something potentially giving even well-versed aficionados pause for thought, while taking a magnifying glass to the sometimes faint and slender lines of linkage mapping rock 'n' pop's connections.
