  We present a fully dynamical simulation of central nuclear collisions around
mid-rapidity at LHC energies. Unlike previous treatments, we simulate all
phases of the collision, including the equilibration of the system. For the
simulation, we use numerical relativity solutions to AdS/CFT for the
pre-equilibrium stage, viscous hydrodynamics for the plasma equilibrium stage
and kinetic theory for the low density hadronic stage. Our pre-equilibrium
stage provides initial conditions for hydrodynamics, resulting in sizable
radial flow. The resulting light particle spectra reproduce the measurements
from the ALICE experiment at all transverse momenta.
