The New Pot Oil in Wrenthorpe Wakefield does a superb open mic night every Tuesday.The best I 've seen yet. Kicks off about 8 15 and is full of young wannabes of a very high standard indeed. The guy who runs it. (Chris) is a great guy and gets you a fabulous sound through the PA. Its best suited to solo acoustic or duo acts. best of all the audience is very quiet, respectful, friendly and responsive....now that is good for ya average open mic. They do have an unsigned band night on Mondays which is more suited to you noisier rockers.
