upcoming exhibition


10 Dec 2022 –  28 Jan 2023  

Opening Reception: Sa 10 Dec 2022, 3p – 6p
Closing Reception:  Fr 27 Jan 2023, 4p – 6p

Liminal: a sensory threshold, barely perceptible or capable of eliciting a response.

Liminality: a liminal state of transition between one stage and the next, especially between major stages in one’s life.

In this exhibition, works in various media explore those unwitnessed or imperceptible states and experiences of transformation. Artists include The Invisibility Collective members Susan R. Kirshenbaum, Rhiannon Evans MacFadyen, Samira Shaheen, Christopher M. Tandy, and invited artists Joseph Abbati, Vin Seaman, Allan Rosenfield, Rell Rushin, Na Omi Judy Shintani, and Leif Larson.

In 2020, The Invisibility Collective presented their first invitational exhibition: Seen × Unseen at Radian. In their second exhibition: Thresholds of Liminality, artists explore the un- or under-perceived process of transition and the moments at which something might happen, cease to happen, take effect, or become true. Acting as revealers, guides, mapmakers, documenters, whisperers, and companions, the artists in this exhibition bear witness to these thresholds, centering experiences whose great meaning is undetectable by those not within the experience of transition.

Additional performances and events will be held throughout the exhibition.

California is an ecosystem with a remarkable range of flora, and an equally remarkable range of artists who work to capture the beauty, intrigue, and symbolism embodied in plant life.

Jennifer Banzaca, Douglas Benezra, Yooseon Choi, Velia de Iuliis, Donald Hershman, J. Iglesias, Dani Jeffries, Linda Larson, Peter Palmer, Peter Sandback, and Curtis Wallin.




12.06.2020 – 02.28.2020  

The Invisibility Collective and invited guest artists assembled an exhibition that is the culmination of months of virtual “Covid Conversations” from the West Coast to the East Coast of the USA.

We are looking at various ways that people express their feelings about being seen and not being seen and the intersection of the two worlds. We are exploring the many aspects of what it means to be invisible and presenting ways of becoming more aware of how this status affects us. Each of the collective’s members has asked questions about their experiences with invisibility. Our inner community is expanding to include a slightly larger outer community circle.

Together and individually we are exploring this intersection of being seen and unseen. The ideas that form the foundation of the collective preceded Covid, but have not surprisingly grown to encompass elements and results of the prolonged pandemic. How often and in how many ways do these words come up in your own conversation? As we’ve probed these ideas sparks have flown and intangible becomes more tangible. We are peeling away layers to look beneath the obvious – to reveal – and to reflect through an art experience that peaks the senses.

Questions are raised. Answers are discussed. It is experiential.

paintings by
andrew lyko

10.05 – 10.26

Lyko’s artwork uses mediums of acrylic, oil bar and spray paint in diverse mediums which awaken our sensibilities to experiences and strokes which stimulate our intense interest. Growing up in Southern California, Lyko was heavily influenced by his childhood in East Los Angeles where he saw and experienced street urban culture and spent many childhood days on his skateboard flying by street graffiti from Shepard Fairey, Mr Brainwash, Invader and Kid Zoom.

Friendly Fire


Group Invitational

Throughout my life, I have somehow had the luck of drawing a remarkable circle of artists as friends. From those I met as a young art student at the University of Michigan, to more recent acquaintances from Burning Man, this show celebrates their lifelong passion for making work that truly moves people.
