I know what 90% of you are thinking. Who the hell is Imperial Teen? And why the hell are they a guilty pleasure?
Imperial Teen is a veritable supergroup, featuring members of The Wrecks, Sister Double Happiness, and Faith No More. They're all multiinstrumental (frequently switching instruments mid-show) and they all sing, making four part boy/girl harmonies possible.
Take this first song, their first single (which MTV mistitled). A song about Kurt Cobain, written in the wake of his death. Notice how three of the four members are singing (Lynn Truell stick to drums in this case), making for a beautiful, densely-layered song.
This next song, from the Jawbreaker soundtrack and featuring a video starring Rose McGowan, showcases a four-part harmony and a different sound. The breathy backing adds almost another instrument and definitely another dimension to a maturing band.
A little more recently, we have the four part harmonies going.... but with the previously silent Lynn Truell on lead. This song, one of my favorites by any band, is a bit nosier than the prior ones. Which might be why I like these guys so much - they're so versatile, and still sound like themselves. And they're not afraid to grow.
