The 1940s - some of the best jazz ever recorded, plus superb blues and country - but that's the US only.

In the UK it has to be the 1960s - The Beatles, The Animals, the Stones, Dave Berry, Hendrix, Cream, psychedelia, the blues boom, John Peel, the folk revival, the ISB, the Bonzos, Ron Geesin, the Oz and IT scene, Marianne Faithfull - the list's endless.
