Volume Four of Four. Booklet in English. EU-only three CD collection compiled and annotated by renowned Blues expert, Bill Dahl. Bear Family Records is telling the story from the beginning of electric Blues into the new millennium. In the 1930s, the invention of Gibson's ES-150 - the first electric guitar - changed popular music forever. The first generation of Blues pioneers played acoustic instruments, but with the invention of amplification, guitar and harmonica players could be heard over the piano, drums and horns. Music was revolutionized. Here's the complete story from jazz-inspired jump numbers in the late 1930s to hard-driving blues/rock from the States and Great Britain in the 1960s, '70s, and beyond.
