A couple of Brits have scooped awards during the preliminary ceremony.

Congratulations to Clean Bandit and Jess Glynne (above), who won best dance recording for Rather Be.

That was a Brit-heavy category - they beat Basement Jaxx, Disclosure, Duke Dumont and (token non-Brit) Zhu.

And dance veteran Aphex Twin won best dance/electronic album for Syro, his first album for 13 years.

The pace has been set by Rosanne Cash (Johnny's daughter), who has scooped three early trophies - best American roots performance, best American roots song and best Americana album.

Other multiple winners so far include Eminem, who's won best rap/sung collaboration for The Monster (with Rihanna) and best rap album (The Marshall Mathers LP2).

Kendrick Lamar also has a double already - best rap song and best rap performance, both for I.

Madonna's arrived and is clearly determined not to get overshadowed by the younger pop crowd.
