This talk will present the results of the azimuthal anisotropy of charged particle production and two particle correlations  in Pb + Pb collisions measured with the ATLAS experiment. The results are obtained with multi-particle correlations and compared with the event plane method. A complete set of v_n harmonics measured from central to peripheral events covers a pseudo-rapidity range of |eta| < 2.5 and a transverse momentum range 0.5 < p_T < 20 GeV. A comparison of the event plane and particle correlation methods allow to uniquely evaluate non-flow effects as well as the size of flow fluctuations. The v_1 flow and scaling of integrated elliptic flow, down to very low-p_T, will be discussed and compared to results of lower energy experiments.
