Thanks to Franss, here's a duet Canadian singer Yann Perreau did with Camille. It's from his latest, just-released album Un serpent sous les fleurs. Hadn't heard of Yann until now - turns out he made four cd's, worked some big names and made some pretty disturbing videos.
And in addition to the post about Seufzmädchen, turns out that Kitty Hoff (pictured) did a duet with Coralie Clement on her latest album. In German!
