[close] B. H. Friedman, who wrote the first biography of Jackson Pollock, returns in "Tripping" to the time, shortly after Pollock died, when the author and wife participated in the early drug experiements conducted by Timothy Leary, the Harvard psychologist. Much of this memoir is based on reports Friedman wrote to Dr. Leary and on correspondence with him and others. The author creates a candid and fascinating portrait of the firsthand effect of "tripping," and the ultimate price some paid when dreams of innocence and liberation turned into nightmares. A true flashback to a turbulent time of excess and exhilaration, "Tripping" is the dramatic account of one man's journey through personal and professional upheaval and toward enlightenment. [close]
