Neatly summarizing Johnny Mathis's half-century as a recording star within a single-disc, 18-track compilation, A 50TH ANNIVERSARY CELEBRATION is a near-perfect summation of the man's career. Equipped with an instantly familiar voice, an easygoing delivery, and a singular grace, Johnny Mathis is perhaps the greatest easy-listening singer of his generation. On this disc, classics like "Chances Are," "When Sunny Gets Blue," and "Misty" are paired with a few more recent tunes, like his version of "Over the Rainbow" with Jane Monheit.
