Like whenever someone passes in the music world, people delve into the archives to find some loose vocal recordings like what happened with Michael Jackson or Freddie Mercury's posthumous albums. Here Sasha Frere-Jones - LA Times - wrote before Bowie's death "There are five more songs from these sessions that have yet to be released. So look forward to next Christmas and hope for a deluxe edition".
