I don't know.
It's the second time I'm listening this work and my sensations are not yet clear..
A moment I think theat the work is a bit rough; and a second later I think that 'm in front of a very good cd.
I've read the description that follow the band history, and perhaps the problem is written there: recording over recording to hide the fact that the band is only a duo. The result is a sensation of rough lacking artificiality. A band is the union of souls, not the union of paths..
But...
The ideas in this album cover this (only) defect. From Crosby, Stills, Nash & Young, to a knoplfer guitar, smooth sound, but originally mixed. A sound that learned from '60-'70, but is able to speak in and for the 21° century.
So, come on les2vains, search for some guys to complete the band. You've get too many good ideas to waste them in a mixer!
