Looking for particular Japanese progrock band

Hello
Recently I discovered a Japanese progrock band, it sounded very fresh, avantgarde mixed with more ear-friendly sounds :)
The trouble is I lost this band and can't find it now.

I was pretty sure the first track was calles "Circle/Line" but can't find it, maybe there's a mistake in it coming from my bad memory, but im sure the "/" was in title.
The album had 5-6 tracks, bout half of them semi-long ones.

Can you help?

Oo, Dean...more speedy than me Japanese.

Circle/Line is the middle track on (I think) three of their albums - perhaps the copy you heard was from vinyl and it was the first track side two.

hmmm can anyone help me with getting this band?
last.fm has no samples, emule has very little sources...

Ah, nice. Big fan of Kikuchi. While I will start my search for Susto, I'll suggest you'll check out his One Way Traveller from 1982, which actually is progressive jazzrock/fusion (opens with a sidelong monstertrack called Alacalder), and the one of the best jazzreleases I've heard recorded in the 80's.

The two albums I got from the early 70's are both closer to avantgardejazz, though 

^If so, surely just son will do (he started recording in the late 80's)?

Dean, I didn't know you were a closet Date Course Pentagon Royal Garden fan. 

I have an album of theirs somewhere that needs playing.

well in that case I gotta check Report From Iron Mountain - only it's hard to find it

but I found One Way Traveller and gonna tell you later what I think about it - thanks for info anyway

Glad you like it. I imagine it can safely be reccomended to most prog/jazzfusion-fans too. Its quite melodic, progressive jazzrock, and not really a difficult listen.
