I have mixed feelings about this recording. Certainly, the prospect of a S&G reunion in their native New York in Central Park was an exciting proposition, and they are supported by crack New York session musicians. The performances are fine, but.....something's just not right. The psuedo-jazz late seventies arrangements seem out of place in some of the S&G 60s classics, particularly the watery electric piano. Makes the performances sound dated...in the wrong era. The most enjoyable songs are the ones where the arrangements are sparsest - Scarborough Fair segues nicely into April Come She Will.
Furthermore, in ways, this is a Paul Simon concert with special guest Art Gunfunkel. There are many Paul Simon songs from his solo years up until that time. Some of the Simon's solo songs don't adopt well to suddenly becoming S&G vehicles, though Garfunkel's reading of American Tune is beautiful. Anyway, this reunion smacks a bit of opportunism on the part of Simon, but I guess he's entitled.
S&G's saga parallels that of the Beatles - they took that particular sound as far as they could, and then it was time to move on. At the time of breakup, I lamented it (I had to deal with the breakup of my two favorite groups within six months of each other). But, like the Beatles, it was the right thing to happen.
That doesn't mean there can't be "reunion" concerts or projects like this one, but it is true that you can never really "go back." I am happy that S&G reconciled sufficiently to make an event like this possible - the Beatles never did - and I am happy that it has been preserved for posterity. But, if you really want to hear what S&G were all about, you really need to hear the original recordings. This is merely a very nice gift to all their fans, and for that we should be grateful.
