Apart from the hovering black cloud - 1,000 metres worth of black electric cables all curled and tangled up - there's nothing to see in 'Cloud/Landscape', German sound artist Christina Kubisch's debut solo exhibition in Hong Kong. But there's a lot to hear.
Put on a pair of wireless headphones and move around or under the 'cloud', and you'll hear mechanical tones of different pitches and textures. Walk over to the window, and the sound of water drops accompanying an excerpt of Schubert's Winterreise adds mood and colour to the concrete landscape of Kowloon Tong outside.
Part of the 'White Walls Have Ears' sound exhibition series at City University's Creative Media Centre, the show, with its minimal set-up, brings to mind works by conceptual artists from the 1960s and '70s. But Kubisch is reluctant to label herself as such.
'Conceptual art is just about the idea,' she says. 'My way of making art is more about getting people into the piece itself, to get them interested in their listening, so that they'll really stay and explore the work.' She says curious listeners tend to get more out of her piece than those who just pass by it.
Staying curious is important to the 64-year-old German sound artist. Her life-long search for the new has kept her art fresh and alive for the past 40 years. And it was her curiosity that led her to sound art long before it was recognised or existed as a discipline.
'There was no possibility to study sound art at that time [the late 1960s]. Sound art didn't exist. So, I didn't know exactly what I wanted to do,' she says. 'But I was always interested in music and visual arts.'
