The 17th annual Air Guitar World Championships have taken place in Finland.

Eighteen contestants battled in front of an audience of 5,000 for the ultimate prize for imaginary instrumentalists.

In the first round, they have to play a song of their choice; those who make it through to the next stage perform a number chosen by the judges.

This year's winner was Justin "Nordic Thunder" Howard from the USA.
