In this article, the non-self dual extended Harper’s model with a Liouville frequency is considered. It is shown that the corresponding integrated density of states is 12\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\frac{1}{2}$$\end{document}-Hölder continuous. As an application, the homogeneity of the spectrum is proven.
