Measurement of the azimuthal anisotropy of charged particles produced in heavy-ion collisions is one of the most powerful tools to study the properties of QCD Matter. An analysis of charged hadron flow in Pb-Pb data taken by the ALICE experiment at $\sqrt{s_{NN}}$=2.76 TeV will be discussed. The event plane [1] was reconstructed using the VZERO detector (two scintillator arrays covering pseudorapidity range 2.8 < η < 5.1 and −3.7 < η < −1.7) whose large pseudorapidity gap from the central tracking system (-0.8<η<0.8) helps to reduce non-flow contributions. Emphasize is given to the azimuthal anisotropy of charged particles, characterized by the Fourier coefficients, up to high transverse momenta. [1] A. M. Poskanzer and S. A.
