Surface Tension

Lennox Dunbar RSA

Layers, marks, and meaning — the shifting surfaces of Lennox Dunbar RSA 

Working across painting, collage and mixed media, Dunbar explores how we navigate the space between order and chance. His layered surfaces, marked by precision and intuition, invite viewers to look beyond structure and find beauty in the unpredictable. Bringing Dunbar’s distinctive visual language to Argyll’s Secret Coast, Surface Tension offers rare insight into an artist whose practice continues to shape and challenge contemporary Scottish painting.

The exhibition reflects SCCOCO’s commitment to connecting national artists with rural audiences, and to celebrating the diversity and depth of Scotland’s creative landscape. Surface Tension forms part of the RSA’s 200th anniversary programme — honouring Scotland’s artistic legacy while looking firmly to its future.

Mach Squared

David Mach HRSA & Robert Mach

A major joint exhibition by brothers David Mach HRSA and Robert Mach.
Known for their bold, playful and deeply human approach to making, the Mach brothers share a lifelong creative dialogue that stretches from Fife to the international stage. This exhibition brings their practices together for the first time in Argyll, transforming Tighnabruaich Gallery into a space of energy, humour and reflection.

Expect large-scale sculptural works, collage, and mixed-media pieces that explore identity, pop culture, and the stories we tell about ourselves. Both artists challenge conventions of material and meaning — from Robert’s intricate constructions to David’s iconic assemblages and installations.

Mach Squared is a celebration of making, connection, and family — part of the RSA’s 200th anniversary programme honouring Scotland’s creative past and future.

Distribution

Tim Sandys

Tighnabruaich Gallery presents Distribution a solo show from our inaugural winner of the Secret Coast Prize for Fine Art. 

Sandys works across sculpture, drawing, painting, film and sound, as well as site-specific installation and public intervention. His work is united by a sustained interest in observation and the social conditions through which meaning is constructed. Underlying this diverse body of work is an approach that draws as much from ethnographic observation as it does from contemporary art practice.

Exhibited nationally and internationally, his practice has received numerous awards and recognitions. He currently teaches painting and sculpture for the Open Studio Programme at the Glasgow School of Art. He is based in Glasgow, Scotland.

In 2019 Sandys was awarded a RSA Residencies for Scotland  with An Cridhe, Isle of Coll and a  RSA Barns-Graham Travel Award in 2015.
