Rapper Anderson .paak is set for his coolest gig ever - performing inside a glacier in Iceland.

The Come Down hitmaker is among the artists booked for the Secret Solstice festival in Reykjavik next month (Jun17), but in addition to hitting the main stage with his backing band The Free Nationals, he will also be headlining the event's exclusive Into The Glacier party.

Described as a "once in a lifetime event", the 18 June (17) bash will feature Anderson braving the cold as he performs inside Iceland's second largest glacier, named Langjokull, to an audience of just 125 people, reports AllHipHop.com.

To get to the party, guests will be "taken under the surface through a man-made ice cave where they get to witness the magnificent 'blue ice' which is hidden deep beneath the surface," reads a press release.

Icelandic rapper Blaz Roca will also be part of the Into The Glacier event.

Secret Solstice 2017 will take place from 15 to 18 June (17) and feature additional acts including the Foo Fighters, Chaka Khan, The Prodigy, Big Sean, and Rick Ross.
