Exploiting a recent European Union Directive extending the term of copyright for sound recordings , Sony released an 86-track collection of Bob Dylan recordings, including studio outtakes and live recordings from 1962-63.

The Directive, issued September 2011, extends the term of protection for sound recording copyrights by 20 years—from 50 years to 70 years. But there’s a catch: the copyright holder must “use it or lose it”—to qualify for protection, the work must be published within 50 years creation. Recordings by many well-known acts from the British Invasion of the early 1960’s—including the Beatles, the Rolling Stones, the Who and the Yardbirds—are bumping up against that cutoff. Sony recognized that the 50-year window’s expiration was approaching and released the tracks, gaining the benefit of the extension.

If not released before January 1, 2013, the works would have been dedicated to the public domain in the EU—free for anyone to exploit without requiring the permission of or payment to Sony, Dylan, and/or anyone else.

The archival release, appropriately dubbed “Bob Dylan: The Copyright Extension Collection Vol. 1.,” includes alternative takes of several songs from Mr. Dylan’s second album “The Freewheelin’ Bob Dylan,” such as “Blowin’ in the Wind,” “Bob Dylan’s Dream” and “I Shall Be Free,” as well as multiple versions of some songs that missed the final cut. There are live performances, as well, including some from the Gaslight Cafe, Carnegie Hall and the Finjan Club in Montreal.

The Directive, named “Cliff’s Law” after the 1960s-era British pop-singer who campaigned aggressively for the extension, is seen as a victory for many aging superstars, including the aforementioned British invaders, as well as American artists like Frank Sinatra, Miles Davis and Mr. Dylan, who recorded in Europe. In an interview with the BBC, The Who’s Robert Daltrey—an outspoken proponent of the extension—explained that to the Directive ensured that artists could continue to receive royalties into their old age. “They are not asking for a handout,” he said, “just a fair reward for their creative endeavours.” Indeed, the Directive’s explicit rationale is to eliminate the “income gap” faced by musicians outliving the 50-year term.
