Description
We present the charged particle pseudo-rapidity density in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV with an extended centrality dependence, and in p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV over a broader pseudo-rapidity range. In the forward regions where the signal
is dominated by secondary particles produced in surrounding material, we use a data-driven correction to extract the charged primary particle density. We compare our results
to predictions of various models, and show that none of these models capture all of the
aspects of the full distribution. This talk extends the previous results reported by ALICE
into more peripheral collisions and with higher granularity for Pb-Pb and broader range
in pseudo-rapidity for both p-Pb and Pb-Pb.
