  We study the thermodynamic behavior of multi-spinning d=6 Kerr-anti de Sitter
black holes in the canonical ensemble of fixed angular momenta J1 and J2. We
find, dependent on the ratio q=J2/J1, qualitatively different interesting
phenomena known from the `every day thermodynamics' of simple substances. For
q=0 the system exhibits recently observed reentrant large/small/large black
hole phase transitions, but for 0<q<<1 we find an analogue of a `solid/liquid'
phase transition. Furthermore, for 0.00905<q<0.0985 the system displays the
presence of a large/intermediate/small black hole phase transition with one
tricritical and two critical points. This behavior is reminiscent of the
solid/liquid/gas phase transition except that the coexistence line of small and
intermediate black holes does not continue for an arbitrary value of pressure
(similar to the solid/liquid coexistence line) but rather terminates at one of
the critical points. Finally, for q>0.0985 we observe the `standard liquid/gas
behavior' of the Van der Waals fluid.
