Pink Floyd Quietly Drop 18 Live Albums From ‘The Dark Side of the Moon’ Era

@fuzztone - I saw that tour at the Spectrum Theater in Philadelphia, and I still have my 'Eclipse: A Piece For Assorted Lunatics' tour program they gave out.... 

This has something to do with public domain and that if these don't get released by the artist after 50 years or something, the recordings are available for anybody to release, no matter how bad the quality, so I supposed they figure better free bad quality from them than having to pay for bad quality from a pirate/bootlegger. Apparently other artists are doing similar things....
