You know this winter "reunion" is going to be a good one when Hawaiian slack-key guitar great Keola Beamer opens it with a stunning original, "Keiki's Dream." Reassembling the artists who defined the Windham Hill sound, Reunion features pianist Liz Story arranging the Spanish traditional "Babe Is Born" for solo piano, Windham vet Alex DeGrassi bringing his graceful acoustic guitar work to bear on "It Came Upon a Midnight Clear," and capo William Ackermann rolling out his trademark steel-string arpeggios on a pensive, minor-key original, "Impending Death of the Virgin Spirit." The man who put Windham Hill on the map, pianist George Winston, contributes a lovely reading of Alfred Burt's "What Are the Signs," and fretless bass wonder Michael Manring tickles the ivories as well as bass on a circumspect "Year's End." More about the symbolism of the winter season than the joy of Christmas, Reunion is classic Windham Hill, meditative and a bit melancholy. Also features Mike Marshall, Ben Verdery, Paul McCandless, and others. --James Rotondi
