Owing to a not-entirely-clear European Union ruling stating that artists must “use or lose” (i.e. officially issue) sound recordings within 50 years of their creation. If they do not, the recordings then go into public domain and become fair game for anyone to release legally without compensating the creator, according to Variety.
The practice began to gain steam around 10 years ago, as early recordings by Bob Dylan, Motown Records, the Beatles, the Rolling Stones and others reached the half-century mark, but because the material wasn’t previously considered strong enough for official release even as an archival item, the artists usually bury them in limited-edition CD collections or brief streaming availability.
Pink Floyd are among the most savvy artists when it comes to the value of their catalog, and two years ago they began essentially repossessing bootleg recordings of concerts from their early career by posting them on streaming services for a few weeks — thus officially releasing them — before taking them down.
Right on schedule, about a month ago, they released another 18 about-to-expire concert recordings on streaming services.

On Dec. 8 Pink Floyd released an expanded, "Special Edition" of their 1970 album Atom Heart Mother.
Pink Floyd’s psychedelic art rock made Atom Heart Mother their first No. 1

Atom Heart Mother, which was released on Oct. 2, 1970, included collaborations with a brass section and choir, paired with one of their most bizarre improvisational moments.
The original album will be accompanied by footage from the band's first concert in Japan from 1971.
The video footage - which will be included on Blu-ray - comes from Pink Floyd's appearance at Japan's Hakone Aphrodite Festival in August 1971. The clips were first included in Pink Floyd's 2016 box set The Early Years.

Atom Heart Mother will include a two-disc package with a 7-inch gatefold sleeve, containing the album on CD and a Blu-ray. The video has been upgraded from a recently discovered tape. There is also a behind-the-scenes mini-documentary included in the set.
