There are quite a few rock bands which I've seen in Zürich, if that's your scene. You just need to know your venues, there are good ones like the Volkshaus, Rohstofflager and ones like the Abart Music Club which are just plain unpleasant. Most of the usual city guides and the Züri-Tipp in the Tages Anzeiger list forthcoming events. For the stuff I listen to I usually need to trek out to the Z7 in Pratteln (that's just east of Basel).
