Asimina Chremos, born 1966 in Toronto Canada, is a Greek-American multidisciplinary artist currently residing

in Philadelphia. Her research in performance improvisation is grounded in Contemplative Dance Practice; particularly the concept of Open Space: “Open Space holds each one of us as we are. It is rigorous because awareness is moving between our inner and outer noticing and we are tracking the nowness of it all.” — Barbara Dilley, This Very Moment

Curt Haworth has been improvising since his days in Santa Cruz CA in the 1980s, and enjoys creating works, structures and free environments. His curatorial interests lie in projects based in real time making. He seeks to place artists together so that the generative material fluctuating between initiation and response leads to states never before imagined. He believes the magic of improvisation lies in the traces inside the material that occur spontaneously, the embodiment of sound and the ex-corporeal vibrations of movement. He encourages the audience to view through the lens of a maker, watching the craft of building work grow though the artists into full-blown expressions. Curt lived and worked in New York City for twenty years before moving to Philadelphia in 2009. He has a BA in Creative Writing from UC Santa Cruz and an MFA in Dance form NYU’s Tisch School of the Arts.  He has created eight evening length works and dozens of shorter works. He performed with the collaborative improvisation group Vitamin C in NYC and toured internationally with David Dorfman Dance from 1990 to 2002, while creating 15 original roles. He has taught and set work as a guest artist throughout the United States, South America, Asia and Europe and is currently a Professor at the University of the Arts in Philadelphia.


Loren Groenendaal in tree by Stephanie Leathers

Loren Groenendaal, a founding and current member of ISOP, is a dancer, improviser, choreographer, creative and somatic movement educator, and curator. She is most interested in creating structures that allow for freedom. She desires more connection and adaptation between people and thus builds opportunities for people to collaborate and create. She particularly values dance and music improvisation because it highlights liveness of humans and the fleetingness of everything. In 2005, she helped found the Mascher Space Cooperative, where she is still a Board Member and Artist-in-Residence. In 2011, she started and continues the Thursday evening Contact Improvisation Jam. In 2013, she started a monthly Philadelphia Underscore, annual Philadelphia chapter of the Global Underscore, and co-founded The H-O-T Series of Philadelphia, a program now organized and curated by ISOP that gives a performance platform for improvised collaborative music and dance in performance. She is the founding artistic director for Vervet Dance through which she presents most of her creative work. She holds an MFA in Choreography from the University of North Carolina at Greensboro, a BA in Dance and Visual Arts from Oberlin College and is a Certified Movement Analyst in Laban/Bartenieff Movement Studies.

Vidiksis’s music has won numerous awards, including recognition from the Society of Composers, Incorporated, the American Composers Forum, Chamber Music America, and ASCAP.

“Having perspective is everything.

But having a singular perspective is not enough.  I want multiple.

Because having a multitude of perspectives and angles requires an understanding of multiple languages.


But the word language is also too singular,

yes? So no, not language.

What I want are multiple vantage points that invite a range of ability.


Having boundaries is important too.

But having a solid boundary is too limiting.

I want to change the shape of the boundaryline.

And in this space I create,

I want the audience to receive a physical sensation. “
