When it comes to the all-night event “Glow,” the numbers say it all — 100 artists, from four countries, in 24 installations, over 12 hours. The event will include installations, performances and multimedia art projects from 7 p.m. Saturday, July 19th, to 7 a.m. Sunday, July 20th, around the Santa Monica Pier.

Led by artistic director Marc Pally, a well-known artist and curator, Glow began as a vision for an outdoor exhibit where artists, unencumbered by the white walls of a gallery, would be able to create engaging, interactive art for a public space.

“We weren’t looking for a meditative experience — people aren’t going to come to the Pier at 3 a.m. to meditate with art,” Pally says. “We were looking for something that had a social aspect to it, that would cause people to interact socially.”

Inspired by the all-night Nuit Blanche (White Night) of Parisian fame, Glow grew as word of mouth spread, says Jessica Cusick, the city cultural affairs manager who is also involved with Glow.

As more artists got involved and the event became of international interest, foreign countries began sending representatives, hoping to outshine the others, Cusick says. With entries from England, France, Taiwan, and Austria, organizers hope to present a world-class night of public displays by top-caliber artists.

South of the Pier at the site of the original Muscle Beach will be Lustre’s “Spirited Sails,” a project by Kalim Chan and Dmitry Kmelnitsky. An audio-visual installation that was based on a previous piece done by the duo, “Spirited Sails” will feature screens wrapped around the metal jungle-gym structures. Images taken in conjunction with Loyola Marymount University students will be projected onto the screens, and will include a surround-sound system for audio.

The Carousel building will play host to the project from the SASSAS and dublab team, “Tonalism.” Playing with visual, audio, and motion, the artists plan to combine two-hour DJ sets, live band performances, the historic Carousel, and projected images for the all-night event. Water and tea will be provided.

North of the Pier on the beach, London artist Usman Haque will present his piece, “Primal Source,” a new project approximately half the length of a football field which “has apparently never been done before, though there are certain aspects to it where we are using proven technology, but we are assembling it in a way that has never been done before,” Haque says.

Inspired by the grunion runs and the idea of life becoming important once a year, Haque says he strove for his project to, “create some kind of feeling of things that are alive.”

“I was thinking of primal scream, and primal soup, and just sort of the idea that people could come together to make these beings erupt, or grow, or swim, or fly.”

The project will feature a large-scale waterscreen projection system to make images appear like a mirage, generated by the noises of the public and its surroundings, according to Haque’s Web site, www.haque.co.uk/.
