I think Paul Simon creates his music for the sole purpose of celebrating himself.
Remember the Mike Nichols film Carnal knowledge? The actors were Jack Nicholson (Jonathan) and Art Garfunkel (Sandy). Specifically, the scene in which Jonathan, after a series of loves and marriages failed, it should be to find a prostitute (Rita Moreno) to whom he confided his problems of sexual failures.
The woman succeeds it excites to with a long, intense monologue with which he recalls that only loves himself.
For me, Paul Simon = Jonathan
Paul said that often does not give importance to demands of people. His cycle at the BAM confirms this. He revisited the Capeman to overcome the old failure, it was autocelebrate with African repertoire, and revisits the quiet railway stations, urban rhythms, and immigrant dreams of his greatest American tunes collaborates "with an extraordinary range of artists to offer three musical constellations "that are OLU DARA, GRIZZLY BEAR, JOSH GROBAN, AMOS LEE, THE ROCHES, GILLIAN WELCH… No trace of ART GARFUNKEL. Paul knows that many people have loved and love the harmonization of Simon & Garfunkel, but has decided to "cancel" that period of his career because to deny the contribution made to its success by the great voice of Art.
I not understand how a brilliant man and sensitive can act with great firmness, ignoring the demands of fans and the feelings of his old friend.
