The folklorist and ethnomusicologist Alan Lomax was a prodigious collector of traditional music from all over the world and a tireless missionary for that cause. Long before the Internet existed, he envisioned a “global jukebox” to disseminate and analyze the material he had gathered during decades of fieldwork.

A decade after his death technology has finally caught up to Lomax’s imagination. Just as he dreamed, his vast archive — some 5,000 hours of sound recordings, 400,000 feet of film, 3,000 videotapes, 5,000 photographs and piles of manuscripts, much of it tucked away in forgotten or inaccessible corners — is being digitized so that the collection can be accessed online. About 17,000 music tracks will be available for free streaming by the end of February, and later some of that music may be for sale as CDs or digital downloads.

On Tuesday, to commemorate what would have been Lomax’s 97th birthday, the Global Jukebox label is releasing “The Alan Lomax Collection From the American Folklife Center,” a digital download sampler of 16 field recordings from different locales and stages of Lomax’s career.
