Usher joins Martin Garrix on stage at Ultra Music Festival...

Fresh off wrapping his European tour, Usher was invited to join Martin Garrix's set at the Ultra Music Festival this past weekend. The pair performed their EDM collaboration, 'Don't Look Down.'

I attended Usher's show on Tuesday. It was good. Seeing him revisit so many of his oldschool hits served up a real treat for us long term R&B heads. I think it's okay for Usher to hop on the occasional EDM song as a feature. I just hope the underperformance of his organic music of last year doesn't push him further into recording songs of a heavily EDM-nature. He will never have another 'Confessions,' but that's not to say he can't put out a decent album later this year.

Thoughts?
