The kiddush that is associated with our Chazan Frankel is not the well-known Lewandowski piece, but a lesser-known piece by Cantor Abraham Katz of Amsterdam. A quick Google search will lead you to the website devoted to Chazanus of the Netherlands called chazzanut.com Amsterdam Chazanut seems to have influenced Chazan Frankel’s unique style. I am told that he owned a collection of records by the late Hans Bloemendal. Chazan Bloemendal appears to be the most widely published Chazan of the German tradition, and some of his work has been released on CD and can be purchased on Amazon.
