We present a next-to-leading-order calculation of W/Z production interfaced to shower Monte Carlo, implemented according to the POWHEG method. Finite width effects, Z/γ interference and angular correlations of decay products are included. A detailed comparison with MC@NLO and PYTHIA is carried out.
