zum Beispiel ausser von Ken Waxman auch von „Michael Jackson“:
The duo of Jan and Julius is like no other. A brace of undulating ungulates, high flying heifers who paradoxically reside at the very core of the earth, they make beautiful music together on love-dancing altos or gargantuan bass saxophone beneath tenor or bari. Germanic but far from manic, these two exhibit a patient, ego-free simpatico that offers joy to any sentient ear in the kingdoms of beast or firmament.
– Michael Jackson (downbeat, jazzwise, chicago reader)
