Just as the album’s title is both brooding and punning, so the music is in a constant flux of what, were it writing, we would call ‘tone’. Grabowsky can seem to create a pastiche of an idiom out of which a deep truth will grow in the improvising, while a more solemn-sounding piece will spawn sly asides and dramatic jolts from the players, or perhaps contain an unexpectedly curdled harmony.
