There are no great books about the Everly Brothers. No classic documentary films. Despite their influence on American pop music, which would be difficult to overstate, or the great, gaping beauty and sadness of their music, we are left with no lasting monuments to their catalog beyond the catalog itself. That, and—along with other personal tributes—this sad, ugly, perfect collage by Ray Johnson, who finished the piece by scratching large Xs across its surface, some weeks before filing it away in a box, folding over a thousand dollars in cash into the pocket of his windbreaker, and diving off a bridge that January night. Critics still debate whether his death was a straightforward suicide or a “last performance.” As if it makes any difference.
