There's something undeniably childlike about In Case We Die, the second album from Architecture In Helsinki. Yet, for every propulsive drum beat or gleeful handclap, there's a sad segue or moment of tender guitar playing. Few bands are able to straddle this line between childhood and adulthood, and to do it, the Melbourne eight-piece take a dizzying detour through genres that even Arcade Fire would struggle to keep up with. On the opener, Neverevereverdid, the listener is sped through opera, classical and jazz before the track collapses in a prog rock meltdown. And all in three minutes, thirty-three seconds. Later, there's the twee mathematics of It's 5 and the cute dance pop of Do The Whirlwind. And yet, from the album's first sounds - funeral bells ringing - to it's last, the theme of mortality is everywhere (ghosts, cemeteries and reincarnation all feature heavily). The feeling is that we should sing, dance and celebrate now, because it might be the last chance we have.
