Bucharest celebrates its birthday this weekend (its 557th, in case you were wondering) with Zilele Bucurestiului. While not quite the hedonistic, no-holds-barred affair it should be, there are a few events that may be of interest.<br /> <br /> Most notable is this free concert taking in Piata Constitutiei. Acts lined up to perform include Zdob şi Zdub, Holograf, Vunk, Bere Gratis, Sore, Loredana, Ruby, Connect-R, Gabriel Cotabiţă, Marcel Pavel, Ovidiu Komornyic, Proconsul and Phoenix.<br /> <br /> It starts at 5pm and will go on until past midnight.
