The Barbican is worth visiting for it's brutalist architecture alone. The concert programming is really diverse; it's home to the BBC Syphony Orchestra, but you'll also find bands like the Dirty Projectors and the National amongst the classical and contemporary composer line up. Plenty of art, dance and theatre too, however, the Conservatory is the real gem that's not to be missed.
I have just recently finished a project installing a drawing for artist Alan Johnston onto the ceiling of the Tate Britain. The experience, although being somewhat taxing on peoples health with long hours and difficult working conditions was fantastic. The mediative and mind altering drawing practice that Alan has created combined with the enthusiasm of a team of talented individuals has resulted in what can be considered a great work of art. It will be open to the public later this year.
