Studies of minimum bias events at colliders and studies of the underlying event probe the behaviour of QCD in the non-perturbative regime. The phenomenology of events in this regime is described by empirical models that take many parameters that need to be tuned to the observed data. The tuning process will be discussed in the context of the new energy regime accessible at the LHC. An overview of recent measurements from ATLAS in the soft regime will be given, with focus on studies of angular correlations between charged particle tracks.
