Unreleased music from several different eras of David Bowie’s long and brilliant career will likely start to trickle out in the next year or two, though a long-rumored autobiography will probably not happen.

A Newsweek article says that according to a person close to the late rockstar, who died Jan. 10 at 69,  there is “a long list of unscheduled musical releases that Bowie planned before he died.”

It’s not known how much of the releases will contain entirely new material and how much will be alternate versions of existing songs, but the article reports that the first of the compilations will be available by the end of 2017 at latest.

A cast album is also in the works for off-Broadway play “Lazarus,” for which Bowie composed the score. The musical, based on “The Man Who Fell to Earth” novel and starring Michael C. Hall, closed last week.

Over the years, the singer had amassed a huge collection of memorabilia and personal objects that inspired him, stored across three warehouses. Many of the objects are on display in the “David Bowie Is” exhibit that launched at London’s Victoria and Albert Museum in 2013, which is currently touring the Netherlands and will then travel to Japan in 2017.  The next cities where the exhibit might tour have not been announced.

Although journalist-turned-filmmaker Cameron Crowe had worked on an unfinished book with Bowie in the 1970s, his long-rumored autobiography or art book “Bowie: Object” look unlikely to be completed, according to sources in the Newsweek article.
