What’s on this week: 14-20 August

Schaerbeek’s poignantly named We Need You Festival puts Brussels musicians and artists to work during the greatest crisis to hit the sector in modern times. The programme includes a wide variety of events, including exhibitions, street theatre, open-air music, comedy and dance and kids’ activities. It’s all free. And don’t forget: They need us, but we need them also. 15 August to 15 September, across Schaerbeek

The expansive grounds of the Rouge-Cloître are home to open-air concerts, theatre, slam poetry and other activities this summer. Bring your own aperitif on Friday evenings, or order a basket of goodies ahead of time from Theatre de la Parole, which is responsible for all this fun. On Sundays, you’ll find more of the same, except of the family-friendly variety. Until 30 August, Rue du Rouge-Cloître 4 (Auderghem)

The Brussels Imagination Club is getting some fresh air this week with a group walk in Tervuren Park. Everyone is invited to join the expat club in the lovely park behind the Africa Museum, with its lake, fountains, sculptured shrubbery in the French style and century-old traces of the dukes’ hunting grounds. Sign up in advance. 16 August 14.30, Leuvensesteenweg 13, Tervuren

While not really a secret, the Secret Rooftop belonging to the Warwick Hotel offers music, drinks and fantastic views of Brussels all summer long. You don’t need to be a guest to access the rooftop bar. Until 13 September 17.00-23.00, Rue Duquesnoy 5

Musician Sofie Vanden Eynde is playing intimate lute concerts this summer at her spacious flat in Molenbeek. Dubbed Renaissance at Twilight, they include the evening concert, followed by bubbles and chocolates. There’s only room for 10, so sign up early. 16, 18 and 30 August

Get in a little dog stretch with Yoga in the Park, a pay-what-you-can session with Lien Romeyns on Sundays. If you don’t have a mat, let Lien know – she has extras. Classes are in English. Sundays 19.15, Parc du Cinquantenaire

Mama’s Open Mic (lovingly known as Mom) is back at Muntpunt for an open-air edition. Discover all sorts of slam, rap and dance at this language-friendly safe space. 21 August 20.00, Munt 6

The Au Bord de L’eau neighbourhood initiative turns a dull patch of grass at the canal in Laeken into a hive of activity every Sunday. Join in with activities for big and small, and step up to the bar to quench your ensuing thirst. Sundays 14.00-20.00, until 27 September, Rue Claessens 1

Cinematek’s Young Film Fans programme offers summer fun for the whole family. Coming up are the hilarious cult classic The Princess Bride, the creative and absorbing Persepolis and the jolly Popeye starring the late Robin Williams. Until 30 August, Rue Baron Horta 9

OUTSIDE BRUSSELS

Before the onset of electric lighting, night-time was a whole other world. Sometimes it was wondrous – an escape from day-to-day realities and social conventions. But sometimes it was dangerous, transforming city streets into battlegrounds. Still today, night feels different from day, even when we’re indoors with all the lights on. We know that beyond our front door is a world we cannot fully comprehend. De Warande’s exhibition De Nacht (The Night) features artists who explore these two worlds that live side-by-side, and yet differ so much from each other. Until 13 December, Warandestraat 42, Turnhout

While René Magritte did not share his photography or home movies with the public, the images – discovered a decade after his death – provide a fascinating insight into how the famous Belgian surrealist saw the world, and perhaps how he prepared a new painting. His keen interest in photography and cinema shine through in René Magritte: Les images révélées, an exhibition of more than 130 works, culled from private collections the world over. There are also photos of Magritte as a child, with his family. Until 20 September, Avenue Paul Pastur 11, Charleroi
