When I was in college, there was a school shooting in San Diego. The shooter's excuse was "I don't like Mondays". The Boomtown Rats, an Irish band, wrote a song about that (I saw them in concert a few years later). At the time, it just seemed absurd. Before I graduated, Lennon was shot and so was Reagan. And now look where we are. As another Irish band asked "How much longer must we sing this song?" Help.....
Royksopp did several other songs with Susanne Sundfor including Ice Machine (a cover of an obscure Depeche Mode song) and If you want me, a beautiful song from their latest album. I also recommend Monument with Robyn. Also note that Royksopp is Norwegian for puffball mushroom.
Aurora lost a love one in the Utoya masscre. She wrote a song about it when she was 15 called The Little Boy in the Grass. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Hkm7rAhi550.html
