Casiokids

Although black metal has been the country’s chief musical export of late, Norway’s all-time most successful band remains ’80s synth-pop outfit a-ha, who announced that they’re retiring at the end of 2010 (what, you didn’t know they were still active?). Earlier this summer – via an American Idol-esque reality show sponsored by a-ha – the “Take On Me” boys passed their torch to upstart Norwegians Casiokids, who won the contest and the accompanying one million kroner (around $160,000). That’s allowed them to finance a U.S. tour, where they can show what they’ve been up to since forming in 2005. That means lots of high-energy, retro electro-pop crafted out of vintage keyboards, strings, toy instruments, weird samples, joyful melodies, and gentle vocal harmonies. With Light Pollution.
