BOB DYLAN: An Intimate Biography By Anthony Scaduto (Grossett Dunlap, illus., $7.95) The nasal whine of Bob Dylan’s voice drives me up the wall; oddly enough, the words he sings stop me in my tracks. Thus, between a mixture of irritation and fascination, I find that the song, and not the singer, is the important thing. And of our own internal and external confusions and ambiguities Dylan has fashioned a notable career as interpreter-song smith. He seems the rein carnation of the ar tist hero when he writes, “I’m ready for to fade into my own parade.’’ For just as every hero whose destiny it is to exist for the rejuve nation of his society, he knew, through personal experience and the collective experience of his time, that man’s “ancient empty street’’ was ‘‘too dead for dreaming.” APPARENTLY, judging from this closely - sketched biography and at tendance at a recent Dylan concert in which an enhanced maturity and poise took some of the edge off his na sal whine, Dylan has found himself in the most profound and personal way possible. For he has realized an un challengeable bit of wisdom — that one man’s way is not, and can never be, another man’s way. In his art, and in his life style, Dylan rose above all imitative patterns and advice to forge his own path. UNFORTUNATELY, Scaduto’s book on Dylan falls far short of the to tal account it should have been. Much of it is dominated by petty gossip and unimportant facts; Dylan comes through, however, in spite of the auth or’s determination to be dull, for he is a subject who cannot be denied place and scope. For starters, however, “An Intimate Biography” (a mistitl ing, obviously) does begin to intro duce us to an artist whose work is li able to cast a long shadow into the fu ture. ROY NEWQUIST Newquist
