Jukes Bar is located on Leonard street and according to their myspace page they have FREE live music every Friday and Saturday night. This is a 21+ venue so don't bring the kiddies. This Saturday the show starts at 9pm. Both websites offer a list of upcoming events so if you can't make it this weekend maybe you can pencil them in another time.
