Amid the glitter and glamour of the Grammys last night a University of Minnesota student adviser and a string musician walked up to claim his prize. Jon Pankake won a grammy for his essay included in the liner notes for the "Anthology of American Folk Music." It's a collection of some 84 songs originally compiled in 1952 by Harry Smith, an experimental filmmaker. Smith chose country, blues, hillbilly and gospel songs from his own record collection, a selection some say evokes a "lost America." Pankake's contribution to the CD re-issue of the Anthology was a personal essay about how Smith's selections influenced and inspired him as a musician and educator. We reached Pankake in New York, where he's still mulling over last night's experience.
