In a cottage just outside the center, Il Covo is one of Bologna's historical sites where some rather historical concerts are held: from local groups and singers to big international stars. You will need a membership card to come here. It consists of bar-pub area with a wide selection of beers and cocktails, a room where there is usually music and DJs and a bigger room where concerts are held. The latter can be a bit suffocating when it's full of people! For the calendar of events it is best to telephone.
