  We study the T-{\mu} phase diagram of anisotropic media, created in heavy-ion
collisions (HIC). Such a statement of the problem is due to several indications
that this media is anisotropic just after HIC. To study T-{\mu} phase diagram
we use holographic methods. To take into account the anisotropy we use an
anisotropic black brane solutions for a bottom-up QCD approach in 5-dim
Einstein-dilaton-two-Maxwell model constructed in our previous work. We
calculate the minimal surfaces of the corresponding probing open string
world-sheet in anisotropic backgrounds with various temperatures and chemical
potentials. The dynamical wall (DW) locations, providing the quark confinement,
depend on the orientation of the quark pairs, that gives a crossover transition
between confinement/deconfinement phases in the dual gauge theory.
