Jess Glynne and Rudimental are just some of the stars performing at the opening day of the MTV Crashes event in Plymouth.
While day two will see Example, Tough Love, Afrojack and Subfocus raising the roof for the Club MTV finale.
And the fans are making their way down to the event too.
Thousands are expected to attend the event.
This will be the third time the festival - which is broadcast around the world - will return on Plymouth Hoe on Thursday 28 and Friday 29 July.
