Check out this experimental ambient music by Augustine Leudar :

It would be classed as ambient/experimetal and some of it is very very strange !
My favourite is Airquake for its oddness but De bells of Nafin has a nice dubby sound.
It uses various new digital techniques such as convolution reverb, spectral morphing, granular synthesis and stereo field recordings.
