  Holographic dualities between certain gravitational theories in four and five
spacetime dimensions and 2D conformal field theories (CFTs) have been proposed
based on hidden conformal symmetry exhibited by the radial Klein-Gordon (KG)
operator in a so-called near-region limit. In this paper, we examine hidden
conformal symmetry of black rings and black strings solutions, thus
demonstrating that the presence of hidden conformal symmetry is not linked to
the separability of the KG-equation (or the existence of a Killing-Yano
tensor). Further, we will argue that these classes of non-extremal black holes
have a dual 2D CFT. New revised monodromy techniques are developed to encompass
all the cases we consider.
