Might be a little bit off-topic, but I personally think the family name of the vocalist (Lie Atjam) is probably of Chinese origin.
In the Netherlands, there are many Chinese descendants who use the full name of their ancestors as their family name. I think that the vocalist may have a Chinese ancestor named Lie Atjam (possibly "李亞章" or something like that).
This may be a good example of cross-cultural communication.
Vocals are not perfect, but the production is good.
