Some of the world's top singers, musicians and recording artists are celebrating the past year in popular music tonight at the 56th annual Grammy Awards.

Chart-topping nominees — including Jay Z, Justin Timberlake, Macklemore and Ryan Lewis, Lorde, Kacey Musgraves and Kendrick Lamar — are expected on the red carpet and at the performance-packed gala itself.

Canadians nominees in Los Angeles include Toronto rapper Drake, crooner Michael Bublé and singer Robin Thicke (a dual citizen as son of Canadian actor Alan Thicke).

The Grammys are administered by the U.S. Recording Academy. More than 70 awards were handed out at an earlier, pre-telecast ceremony, hosted by Cyndi Lauper.

The Grammy broadcast takes place Sunday evening at the Staples Center in Los Angeles. Hosted by performer LL Cool J, it begins at 8 p.m. ET and airs on CBS and Citytv.
