The newest Hellogoodbye album, Everything is Debatable, illustrates the tremendous growth the synth-pop group has seen since its first full-length, 2006's Zombies! Aliens! Vampires! Dinosaurs! A quick listen to the debut sees a band that's overtly adolescent, one that would fail to garner an audience by playing at a bar. Nowadays, the band is ostensibly chillwave with a vigorous nod to Passion Pit, a sound that might be far more welcomed.
