‘Illusion, the idea of presence, our perception of reality and the virtual are all equal when I think about this piece,’ says Heather Lander of her new sculptural video installation Materials and duration 1.2. ‘What we see, hear, know and even what we physically touch is all so malleable and personal.

The piece is essentially exploring this idea.’ The first version of the piece was created while Lander – who helped set up the infamous Chateau space many years ago – was on the MFA course at Glasgow School of Art, during which time she won the Bram Stoker Medal.

‘The video content is an amalgamation of documentation of earlier work, namely the ‘Screen sculpture’, which I originally assembled during my 1st year on the MFA,’ she says. ‘This content’s projected onto the ‘Materials and duration 1’ sculpture, which is a layered series of transparent sheets suspended from a steel armature. The room will be saturated with colour - light, dark and sounds of classical instruments abstracted.’

She’s collaborated with Pete Sach on the classical composition elements of this latest version of the piece, and with the visual aspects she’s aiming for something more hyperreal and abstract, because ‘creating this ambiguity makes me think about how one actually tells the difference between what is real and what isn’t.’
