Klarafestival Box: the smallest concert hall in the world is touring Brussels with an intimate listening experience

Some of Brussels' most impressive venues, from Flagey to La Monnaie, Bozar to Kanal, will welcome classical music fans in their hundreds during this year's Klarafestival.

But the festival is also offering a very different, much more intimate, listening experience. The Klarafestival Box is a 15m² glass container just big enough to fit a grand piano that will be touring the neighbourhoods of Brussels over three weeks. Audience capacity: three.

Billed as the smallest concert hall in the world, the Box offers a unique (and free) opportunity to enjoy an up-close-and-personal live classical music performance. The aim is simple: to get classical music out of the traditional venues and open the genre up for new audiences to discover, in an unusual setting.

After exceeding all expectations with its debut outside Flagey last year, this time the Box will be bringing classical music to different neighbourhoods. From 14 March it will be set up on the Place de la Monnaie in central Brussels, then from 19 March on Avenue Louis Bertrand in Schaerbeek and from 25 March on Place Cardinal Mercier in Jette.

In total, 26 performers are scheduled to play in the Box over the course of 16 days. Each concert can take a maximum of three people. But if you only book one seat, you won't be placed with two strangers - instead you'll have a concert entirely for yourself.

Each performance will last 15 minutes, with time at the end to speak to the musician(s). Who you get tickling the ivories of the grand piano, and whether there will be an accompaniment, will remain a last-minute surprise.

Your own intimate concert needs to be reserved online in advance - and if last year's Box debut is anything to go by, places will disappear fast.
