Looks like Portland Trail Blazers star Damian Lillard was busy this off season, but not just with basketball. He’s been recording an album. The NBA All-Star unleashed his debut album this week titled The Letter O.

Lillard tells NBA.com that he recorded the project in a week. “I recorded the entire album in L.A. and it took me one week. So I was there for five days and from 12 noon to 12 midnight I was in the studio. I’d workout at 8 am and then I’d go lift and then I’d go to the studio, 12 to 12, five days straight.”

The 12-track album features an impressive lineup of guests as well including Juvenile, Jamie Foxx, Lil Wayne, Marsha Ambrosius, and others.
