VIDEO: The Icelandic hand-clap broke out at Longitude last night

You've got to love Longitude.

Kendrick Lamar was on fire in Marlay Park on Friday night, with the crowd loving every minute of the Compton rapper's set.

JOE's Justine Stafford was on hand to film the crowd doing the Icelandic hand-clap before Lamar reappeared for his encore.

Just one of a number of great moments in Rathfarnham. Anyone else nostalgic for Euro 2016?
