We construct explicitly new solutions of type IIB supergravity with brane
sources, the duals of which are N = 1 supersymmetric field theories exhibiting
two very interesting phenomena. The far UV dynamics is controlled by a cascade
of Seiberg dualities analogous to the Klebanov- Strassler backgrounds. At
intermediate scales a cascade of Higgsing appears, in the sense that the gauge
group undergoes a sequence of spontaneous symmetry breaking steps which reduces
its rank. Deep in the IR, the theory confines, and the gravity background has a
non-singular end of space. We explain in detail how to generate such solutions,
discuss some of the Physics associated with them and briefly comment on the
possible applications.
