Spectacular Icelandic lava tunnel provides backdrop for electronic duo Warmland's album launch

At part of Iceland's Secret Solstice festival, synth pop outfit Warmland launched their debut album Unison Love on Saturday, in the otherworldly setting of a lava tunnel. Supported by homegrown pop songstresses Rokky and Bríet, the duo treated the audience – who donned hard hats and waterproofs to brave the tunnel's hostile conditions – to stripped-back renditions of their recent hits, including a gorgeous, drumless take on new single "Further". The cave's cathedral-like reverb was a great match for Warmland's expansive, synth-led sound, with the surrounding rock face illuminated by brightly-coloured lights and flashes of strobe.
