Phil Everly died this week. The close harmony that was the inspiration for so much of early rock & roll, including many of the artists of the British Invasion of the 60s ( The Beatles, Hollies, etc.), died with him because no group has ever able to recreate the magic of the Everly Brothers.
I could have included a clip from one of their many hits, but here is their version of the beautiful “Kentucky”. It highlights their angelic harmony.
