Ultimately it’s a curiosity that sounds like nothing else.

“[…] On Next Delusion by Berlin-based saxophonist Boris Hauf, […] forms […] an even more unconventional lineup. There can be few instrumentations that are completely novel, but three horns matched with three drumsets recalls few precedents. Waxed on one of the German’s regular trips to Chicago, Hauf has assembled a talented crew, though their abilities are almost totally sublimated to the leader’s offbeat conceptions.
For much of the time, the three percussionists (Frank Rosaly, Steven Hess and Michael Hartman) are so restrained as to be subliminal and the horns (Keefe Jackson, alongside Stein and Hauf) aren’t much more demonstrative. It’s largely impossible to tell who does what in the four tracks, which defy categorization in their execution of Hauf’s austere and rigorous charts. Dissonant unisons and subdued drones characterize the horn lines, which often sound on a parallel but unconnected track to the rumbling massed drums. Ultimately it’s a curiosity that sounds like nothing else.”
