Truth is, Simon did solicit some help from producer (or, as the album's liner notes put it, "sonic landscaper") Brian Eno, who brought along his bag of quasi-electronic tricks to color Simon's folk-pop structures and sweet, emotionally complex voice; together, they crafted Simon's most satisfying release since Graceland. Simon recently turned 64, to considerably less fanfare than Paul McCartney received; accordingly, much of Surprise deals lyrically with aging and mortality -- hardly new themes for the singer, but he pulls it off more artfully and incisively than he has in a long time, using his trademark combination of humor and dolor. These new tunes should be as much of a joy to hear live as any from Simon's illustrious songbook, including the handful of Simon & Garfunkel gems he's sure to break out.
