Ulf Ivarsson is a Swedish bassplayer, Producer and composer from Stockholm.
He produces experimental, dub, ambient and avantgarde music. 
The album Nammu is a coöperation with Bill Laswell.
Per plays keys on this album. 
First release was on cd, but later also on vinyl in the USA.
I got my vinylcopy straight from Ulf when he got a few copies to sell from Sweden.
