Hi everyone, thanks for your replies.
For N.Bentzon, I found his official site
http://nikolajbentzon.com/
, but unfortunately there is no specific reference or info to his early olufsen outputs. (btw, he is the son of Danish contemporary composer Niels Viggo Bentzon).
His projects are acoustic piano trio & solo, electric funk group, w/vocal and w/orchestra. I can see he is a busy musician.
On youtube, many videos are found. They're uploaded by mr.bentzon himself. 2 good tunes:

(thanks Margaret for the link, the live is funky & crisp)
Most of his playing in acoustic format seems to be in a bop way rather than in b.evans one, inclining to a fast swigin or busy, intensive side(not so heavy though).
I personally prefer modern-to-contemporary jazz(modal, evans, ecm, brooklyn school, ...etc), but it's fun to listen to. I'll keep looking for his olufsen cds.
For other danish jazz musicians, I can find lots of samples on amazon & itunes and videos on youtube. some choices:
older tunes by B.Axen B.Jaedig A.Botschinsky, NHOP, A.Riel....
