Experiencing this documentary without encountering any advance hype is like stumbling into the cozy Greenwich Village shop of the title: it’s a ride down the rabbit hole to a world of unexpected and singular pleasures. Rick Kelly is the rock-steady proprietor and artisan who handcrafts guitars from reclaimed old wood (much of it from demolished Manhattan buildings erected during the late 19th century); his punk platinum blond apprentice Cindy Hulej decorates the instruments with intricate calligraphic designs; and his nonagenarian computer-savvy mother, Dorothy, runs the office. Musicians who drop in, swap stories, and play some tunes include Nels Cline, looking for a birthday gift for his pal and Wilco bandmate Jeff Tweedy; jazz innovator Bill Frisell; Patti Smith’s veteran sideman Lenny Kaye; Lou Reed’s buddy Stewart Hurwood; urbane Captain Kirk Douglas of The Tonight Show‘s hip-hop house band the Roots; Bob Dylan band member and session artist Charlie Sexton; and the charismatic, multifaceted Marc Ribot. Producer-director and pop culture enthusiast Ron Mann, the Canadian director whose close observation, gentle humor, and wide-ranging curiosity distinguish such nonfiction films as Comic Book Confidential (1988) and Grass (1999), credits Jim Jarmusch as the movie’s “instigator,” and Jarmusch obligingly pops up, looking every inch his hipster self. Toronto rock ’n’ rollers the Sadies provide additional music for the film’s seductive soundtrack.
