This Chicago-based band continue to be every bit as stylish as the Eames furniture they took their name from. On this, their follow-up to the brushed-chrome electronica of their 2000 album Pelo, siblings John and Frank Navin return to the more naturalistic celestial beauty of their earlier efforts, where the listening may be easy on the surface but is actually quite difficult beneath. As on the loungy "I Blow You Kisses," where John coos "If you were sinking in a lake/And I threw you a lifeline/would you let it float away?" over a gently bobbing melody. Or on "Pop," where the sound lives up to the title sonically but the lyrics are about a person who’s just too out of it to maintain a friendship. "We’re Both Hiding" sets a painful tale of disconsolate lovers to a sweetly Bacharachian melody. And the narrator of the percolating "Oxygen" is clearly hallucinating from a lack of the title entity. So it goes, with bleak themes playing themselves out against sunny new-wave melodies bolstered by witty, often abstract turns of phrase. The deliberately misspelled album title says it all — this is happiness with a twist.
