For several years now Re:Public has proudly won the title of Minsk's best concert club. They host concerts by some of the best Belarusian and foreign bands, as well as lots of other activities.
They host parties that go all night long, concerts, grindhouse movie nights and festivals. Although in my personal opinion the sound quality is far from good, it's still a popular venue for locals (mostly students) who come here for good music and a great time.
It's not open every day so check the schedule on their website. Also, tickets often sell out so it's wise to buy them in advance.
