As one reviewer on iTunes said, the lead singer, Kazu Mikano, offers up a soothingly indecipherable croon, a nice way of saying she sounds great, but I have no idea what is being sung. Yet, like Bjork, the pure tone and melody is entrancing.
I can't vouch for the rest of the album or the six others iTunes reports the band has delivered, but I expect "23" will be rotating on my playlist for weeks to come before fading down the inevitable road to obscurity.
