It was five years ago Sunday, January 10th, 2016, that the world lost David Bowie.Bowie’s death followed a private 18-month battle with cancer, and according to reports from insiders in the Bowie camp, the music legend died from liver cancer, after suffering from a handful heart attacks in recent years. Bowie was survived by his wife of 23 years, supermodel Iman, his son, movie director Duncan Jones, and his daughter with Iman, Alexandria.

In celebration of what would have been David Bowie’s birthday today, two previously unreleased cover versions are set for single release. The birthday offering includes a version of John Lennon’s 1970 solo classic, “Mother,” which Bowie tracked in 1997 and 1998 for a Lennon tribute collection that fell through, and Bob Dylan‘s 1997 Time Out Of Mind classic, “Tryin’ To Get To Heaven,” which Bowie recorded in February 1998 during the mixing sessions for the LiveAndWell.com album.

Although tributes were literally non-stop in the days and weeks following Bowie’s death, perhaps the most touching tribute was in July 2016 when Bowie’s 1974 classic “Rebel Rebel” took on Herculean proportions when it was played in unison by over 1,000 musicians. A professionally filmed clip of the volunteer-based rock band dubbed Rockin’ 1000 performed the song in Cesena, Italy’s Orogel Stadium.
