Izzy Young, whose Greenwich Village shop, the Folklore Center, was the beating heart of the midcentury folk music revival — and who in 1961 presented the first New York concert by a young Bob Dylan — died on Monday at his home in Stockholm. He was 90.

His death was confirmed by his daughter, Philomène Grandin.

Anyone wanting to capture the essence of the times could do far worse than head to the Folklore Center, at 110 Macdougal Street, between Bleecker and West Third Streets. Established in 1957, it was nominally a music store, selling records, books, instruments, sheet music and fan magazines, most sprung from sweat and mimeograph machines, like Sing Out!, Caravan and Gardyloo.

In actual practice, the center was also equal parts hiring hall; Schwab’s Pharmacy, where young hopefuls awaited discovery; matchbox recital space for organized performances and impromptu jam sessions; nerve center for gossip on a par with any small-town barbershop; and forum for continuing, crackling debate on the all-consuming subject of folk music, which thanks in no small part to Mr. Young was enjoying wide, renewed attention.

“I began hanging out at the Folklore Center, the citadel of Americana folk music,” Mr. Dylan wrote in his memoir “Chronicles: Volume One” (2004), recalling his arrival in New York in 1961. “The small store was up a flight of stairs and the place had an antique grace. It was like an ancient chapel, like a shoebox sized institute.”
