It sounds like an interesting rendition of “
Love is Blue” but as for the performing artists, I know not who (sorry, couldn’t resist…)
Anyway, Jane had some good suggestions but there is also
this guy and his friends that got together to create
The Goat Rodeo Sessions. Or his
Hush album may fit your requirement better. But anything from him is worth hearing.
And to go to the fringe, there are
these guys that have some interesting music although many songs may not be within your chamber-like music definition. But songs like
this and
Last Chance To Dance Trance (Perhaps) may come close.
In any case, tell us what you find and/or find out about that song.
