What's on this week: 30 September-6 October

Multilingual and multicultural, Brussels is said to be the crossroads of Europe. Even before the arrival of the European institutions and Nato, the capital was a melting pot comprised of Belgium’s distinct linguistic groups as well as successive waves of immigrants. Now, of course, Brussels boasts residents from over 180 different countries. The city’s new Mixity initiative is a year-long celebration of all this diversity. This week’s free music festival Hello Mixity, featuring 120 artists of 20 nationalities on two open-air stages, is a mere taste of what’s in store in 2017, when Mixity begins in earnest.

Having sold out Passa Porta in a second, American author Hanya Yanagihara has been moved to the much larger Flagey. She will discuss her short but eventful literary career. After paying her dues as a book publicist and travel journalist, Yanagihara published her first novel, The People in the Trees, in 2013 to encouraging reviews. Her second novel, last year’s A Little Life, was a bona fide bestseller. Hailed as “the great gay novel”, the book made the shortlist of both the National Book Award and the Man Booker Prize. The discussion, in English, is moderated by Flemish radio personality Ruth Joos.
6 October, 20.15, Flagey, Brussels

The second edition of the Brussels Biennale of Modern Architecture, titled Modernisms Are Shaping the City / Modernisms Are Shaking the City, explores the urban landscape of post-war Brussels. The capital underwent a profound transformation after its liberation from German occupation in 1944. Smaller shops and houses were cleared to make way for large-scale infrastructure, office buildings like the Tour du Midi and high-rise apartment blocks. Each Saturday in October, visitors can participate in a different themed tour in Dutch, French and English. The programme also includes one lecture and three film screenings, all held during the week.
1-29 October, across Brussels
