The tuba's bass sounds are in complete contrast to the higher pitches of the spinet, bringing to mind cartoon images of an elephant and a mouse. But none of that concerned Hübsch and Schiller when they first played together in 2008-09; they felt a strong connection in their playing - it remains obvious here. Both have modified their instruments, in the process getting rid of the seeming disparity. Schiller's spinet has become a semi-percussive instrument, amply illustrated by this CD's opening sounds which are most reminiscent of the clacking of a typewriter. Elsewhere, it sounds more like prepared piano—or even a detuned guitar.  In similar fashion, the tuba produces notes far higher than its stereotypical oom-pah, the result of Hübsch's breath control and circular   breathing. Put that all together and it is certain less than one person in a hundred could correctly identify the instrumentation here.   Be that as it may, the dominant factor is that strong connection that Hübsch and Schiller recognised in each other. It means they produce subtle music that is both sympathetic and beautiful.
