A while back, I wrote about a band called Mr. Frederick that combined disparate genres like rap-metal, folk and chamber pop. The Speed of Sound in Seawater is similarly confusing, but in a more insidious way. Listening to their second album, Red Version, their weirdness sneaks up on you. For the first song, they sound like a twee-pop band with a singer who sounds a little like Ben Gibbard. Then the compositions start getting a little more complex, and by the end of the second song, the singer's screaming. The rest of the album continues in this vein of math-twee-pop interspersed with bits of hardcore vocalization. It's legitimately surprising stuff. And a little creepy, if you ask me, but I couldn't tell you why. Go figure.
