We study a number of realizations of axions existing in a multi-`throat'generalization of the warped throat geometry of a Randall-Sundrum slice of$AdS_5$. As argued by previous authors, the problem of generating a suitable,phenomenologically allowed Peccei-Quinn scale is simply and elegantly solved bythe warping. In compactifications with two or more throats it is possible tosimultaneously solve the Standard Model hierarchy problem by theRandall-Sundrum mechanism while implementing interesting warped axion models.The constructions discussed are related to holographic duals of previouslystudied models of composite axions arising from strongly coupledfour-dimensional dynamics.Comment: 14 pages, 1 figure, references adde
