Thank you people i just ordered 3 Heldon album, listen to yours advice, made some internet search, tried to have albums from different periods so i just bought:
the first Electronic Guerilla because of gilles deleuze and also read there is much guitar/eletronica la "no pussyfooting" style
a mid period one who is described in various sites as the most improv and the most various, the most messed up also: Agneta Nillson
was a bit a hard choose between the last two, "interface" and "stand by", they seem their most loved album. The thing that make me choose "Stand by" is that somewhere i read there is a track compared to the track Red by King Crimson. Maybe i choose wrong!
Should receive the records (japan imports) the next month.
Now, while we are at, King Crimson, were a very frustrating band, innit? You can delight or puke at the camp of most classic progrock but Fripp was an awesome guitarist and in a few of KC lps there are a few spot of very great music next to very awful songs.
Take "Red", the track, is something extraordinary, heavy me

tal Bartok, incredible, why didn't they made all the album so? the rest of Red the album is in comparison, some exception there and there, weak.
It's no mystery Fripp best work was when he played for other people.
