Last night, esctoday.com co-hosted the first of two massive Eurovision Song Contest preview events. Eurovision in Concert took place in Zaandam, The Netherlands, featuring performances by seventeen of this year's competing nations. Next week, five more will rock London with a mega-party featuring performances for their Eurovision Song Contest entries and much more.

The first videos from last night's event are now online. You will be able to see more videos and interviews with the participants throughout the day as we continue to prepare and add them to the website.
