Danish electro folk-rock trio Efterklang are busy prepping for the release of fourth studio record Piramida.

‘Hollow Mountain’ is the first and opening track off the forth-comer, which features South Demark’s 60-piece girls choir, coming together to create a grand affirmation.

Piramida is out on September 24 through Rumraket. Pre-orders are open now via the band’s webstore.

Before you go, take a look at this amazing performance by Efterklang at the Sydney Opera House back in May:
