The first of these is expected to be released before the end of 2017

David Bowie prepared a number of records to be released in the years following his death, according to reports.

Newsweek writes that the records are “divided into eras” and will be released in the years to come, starting in 2017. They “will not necessarily be released in chronological order”, however.

It is also not known whether or not the new releases will feature any unheard music recorded by Bowie, but the news comes soon after Tony Visconti, Bowie’s longtime producer, revealed that Bowie had demoed at least five songs in preparation of a new album. A Newsweek source says, “Bowie was one of those artists who was very engaged and liked to control what was released from the vault.”

There will also be a cast album for Lazarus, Bowie’s off-Broadway musical, which opened in December and stars Cristin Milioti and Michael C Hall.

Since the news of Bowie’s death his music has seen a 5000% increase in sales in the USA. He remains at Number One on the UK Album Chart for a second week running with his final album ‘Blackstar’, which was released on January 8, two days before his death.

The Official Charts Company announced yesterday that Bowie dominates the UK Albums Chart for a second week, with ‘Blackstar’ staying at Number One and nine Bowie albums in the chart in total.

Compilation album ‘Best Of Bowie’ is at Number Three, 2014 best-of ‘Nothing Has Changed’ is at Number 6, while ‘Hunky Dory’, ‘The Rise And Fall Of Ziggy Stardust’, ‘Aladdin Sane’, ‘The Next Day’, ‘Low’ and ‘Let’s Dance’ are also in the Top 40.
