The results on directed and elliptic flow for Pb + Pb at the full energy of
the SPS (158 GeV/A) and from the first year of Au + Au at RHIC
(sqrt{s_{_{NN}}=130 GeV) are reviewed. The different experiments agree well and
a consistent picture has emerged indicating early time thermalization at RHIC.Comment: 4 pages. For the proceedings of the International Workshop on the
