I can’t figure out if this is real Denglish, or contrived, "I know it’s wrong, I just think it sounds cool" Denglish. But I like it.
I also like the name Gwildis. Sounds vaguely Austrian — they seem to have more odd consonant combinations than Germans.
Also, according to his website, he seems to be a pretty entertaining live act.
And finally, in the picture for the album cover what the hell is he holding? An inverted pomegranate? A grossly oversized hand-knit Christmas ornament? Some sort of Austrian folk emblem?
