Irwin Silber, 84, who as founding editor of the small but influential magazine Sing Out became a towering figure in the 1960s American folk music renaissance that brought Bob Dylan, Arlo Guthrie, and numerous others to prominence, died Wednesday at a care facility in Oakland, Calif., of complications related to Alzheimer's disease.
Mr. Silber founded Sing Out in 1950 with folksinger Pete Seeger and musicologist Alan Lomax. He also published more than a dozen books, wrote for several other publications, and produced numerous folk music concerts.
