In a secluded hutong, Dusk Dawn Club is the place to catch small and mid-sized bands, from post-rock noise outfits to folk strummers, both Chinese and international. Established by a collective of local musicians, artists and curators, there are shows most evenings; check the website or Facebook for listings.
The courtyard bar is also a good place for a drink, with a selection of Beijing craft beers on tap and cheap cocktails.
