Goldfrapp are amazing. They are electro and quirky. You'll probably know some of their stuff if you are UK based.
They have 3 albums at the moment-
Felt Mountain- kinda haunting, more eclectic and strange than the others
Black Cherry- amazing! Very funky, sorta dirty and sexy vocals. Totally reccommend.
Supernature- more commercial, great dance songs.
Onetwo are also quite good. They were the support act for Erasure, but are verrrrry different sounding. They are made up of Paul Humphreys (OMD) and Claudia Brucken on vocals. Their CD is kinda cool.
Here's their site....
