WATCH: David Bowie's Eerie 'No Plan' Music Video Released on What Would be His 70th Birthday

Blackstar won Best Alternative Music Album, Best Engineered Non-Classic Album, and Best Recording Package, while the title track won Best Rock Song and Best Rock Performance -- a complete sweep for the 17-time nominee.

Bowie had only one previous GRAMMY win, taking home Best Short Form Video in 1985 for "Jazzin' for Blue Jean," as well as a GRAMMY Lifetime Achievement award in 2006. The Chainsmokers and Katharine McPhee accepted the Best Rock Song award on his behalf, with McPhee declaring, "His music is forever."

Afterward, Bowie's son, Duncan Jones, tweeted, "So proud of you dad! Would hold you up forever."
