The two releases are pretty much identical; all that distinguishes them is that the colour is darker on the UK one, which also has a sticker on the front bearing the title: Momus Joemus (release date mid-November, available on Amazon for pre-order now, UK edition and US edition).

Whenever a Google Alert tells me an emerging band is being compared to me, I make a point of listening to their music. The alerts usually concern Stars or Black Kids reviews, but this week I got directed to a pretty nice album by Konrad -- one Jeffrey Konrad, in fact, a native of Rock Island, Illinois (with a little help from friends playing circuit-bent turtles).
The album is called Loose Canyons, the review that likens it to me is here, and you can hear quite a few tracks from it on the Konrad website. Konrad himself doesn't namecheck Momus as an influence, by the way; he lists Eno, Devo, Apples in Stereo, Hot Chip, Mountain Goats and Dan Deacon. It also reminds me of a little-known band from earlier in this decade, The Busy Signals. Whatever ghosts are in it, the Konrad album has come out pretty well, I think.
