Someone told me efterklang were Danish... maybe they were wrong.
Efterklang is danish, not dutch, why is it that people can't tell the difference?
oh well Denmark has a good deal of good bands, including Mew, but also:
Under Byen - these guys and girls cannot get enough praise, I can't really describe them, they have to be experienced, though like most of the bands on this list, their records are only available in Europe.
Moon Gringo - recently disbanded indiepop band, but their two records Boy Girl Beat and their newest Ingrid Superstar are among the best indiepop I ever have heard.
Kitty Wu - dark ominous sparse rock'n'roll with really good lyrics
Kashmir - In their early days they were a form of funkrock band with witty lyrics, now they have matured quite a lot and made a milestone(in Denmark at least) with their album The Good Life, which some described as their Dark Side of the Moon.
A while ago came Zitilites out, which was also quite good, they may be my favourite band ever, though I seldom listen to them. It's just nice to know they are there
epo-555 - danish shoegazer at it's best, gorgeous melodies and just the right kind of ghostly vocals
ENTAKT - A demoband, but never the less, they are pretty good and their vocalist kick ass, I don't know how to describe them, may be a little triphop-influenced?
Sorten Muld - I think they are disbanded, but they made some really good electronica records with adapted old danish ballads of bloodshed and dwarves and soothsayers, that may sound strange, but it's in danish so... anyway they are good.
