Even his childish Gambino classmates say they are not sure of his whereabouts on Grammy night.
"This is America" won the record and the songs of the year, two of the three largest categories. Goranson says he tried to call Gambino after the show but did not pass. He says he will try again.
Riley Mackin, the song mixer engineer, said he recently saw Gambino when they worked in the studio a few days ago.
"He's out and I have not seen him since," said producer Riley McCain.
Asked if Gambino's absence is strange, Makin said, "Everything Donald does is a little weird." ]
