Pink Floyd fans are in for a treat. The band quietly released 18 live concerts that are available to stream.

You can find them in concealed locations. On Spotify, for example, they're located in the compilations area, Variety reports.

Pink Floyd releases new Dark Side of the Moon performances from the '70s

This new “concert drop” features the band performing just days after their masterpiece, Dark Side of the Moon, was released. The concerts start on March 6, 1973, and go to November 4th.

Unfortunately, the audio quality of some shows isn't the best. Still, it's intriguing to listen to. You even hear angry audience members, such as in Hollywood, Florida, who were upset people wouldn't sit down. It makes for interesting listening for any Floyd fan who wants to reminisce about being at these earlier shows or wished they were around to attend one.

Pink Floyd has had decades-long conflicts with each other, but they must still agree to release these bootleg recordings. Releasing some of these concerts started a couple of years ago. Thus far, the trend has been to post these concerts and remove them. Last year, they dropped 18 concerts from '72, in which you can hear the band tweak and develop the iconic Dark Side album.

The reason for releasing them (and then taking them down) is for copyright. The music is published before the copyright expires so that bands can “officially” release it, making it theirs. Companies must lawfully publish within 50 years after the performances were made, or the copyrights would be lost.

Whatever the reason, the hardcore Pink Floyd following is glad to have new concerts emerge. Even with rough quality recordings, audience heckling, and all things that make for a great remembrance of what it was like to hear one of the biggest bands of all time.
