Lelavision Physical Music — the hard-to-define Island performance duo comprised of Leah Mann and Ela Lamblin — will roll out a sneak preview of its latest creative endeavor this Saturday.

The performance, “Above the Genome,” is the latest offering in Lelavision’s series of collaborations between Lelavision and scientists from across the United States.

The performance, created in concert with Emory University biochemist Arri Eisen, explores the science of epigenetics — the study of how factors such as pollution and post-traumatic stress disorder can impose genetic changes in people and their offspring.

But according to Mann, who has contributed her trademark choreography to “Above the Genome,” the performance will also be accessible and entertaining, despite its heady subject matter.

“We think you’ll like it all the way down to your DNA,” she said.

A huge new musical instrument, made out of tubular bells and large blown glass pieces by Lamblin, will have its debut during the show, and there will also be other live music composed and performed by Jason Staczek and Garth Reeves.

A panel discussion by local scientists and health practitioners will also be woven into the show.

“If the idea of your genes being a reflection only of their potential, not their destiny excites or intrigues you, come check it out,” said Mann.

“Above the Genome” will be presented at Lelavision’s studio at 7 p.m. Saturday, Nov. 20. The performance is a benefit to help Lelavision continue to develop the production. Tickets are $15 or “pay what you can,” and reservations are required in order to get directions to the studio — call 329-3724 or e-mail lela@lelavision. The show will also be performed at 1 and 3 p.m. Friday, Nov. 26, at the Museum of Glass in Tacoma.
