This is my Woodstock ’99. For four days, the Los Angeles County Museum of Art will host live music, children’s storytelling, a screening of the new Hairspray, the just-opened exhibition Dan Flavin: A Retrospective and the Vernisage of Construct in the Boone Children’s Gallery where families can do just that.

And it’s all free.

The festivities commence on the summer solstice, June 21, with the annual Late Night party (also free) from 7 p.m. until 3 a.m. There’s a surfeit of celebration happening this evening, and I urge you to log onto LACMA’s Web site, to get a full syllabus of the crepuscular entertainment.

While the museum has hosted Late Nights before, Dan Flavin’s illuminated fluorescent installations seem the ideal fixture for this artistic hootenanny; the soft green, yellow and blue glow invokes the same hallucinatory nightlife ambience of MOCA’s equally grand Ecstasy celebration.

Once your eyes are sated, head outside to performances by the Rebirth, DJ Steve Aoki and KCRW favorites Ima Robot. If you’ve seen the Dadaist video for “Dynomite,” you know of the band’s artistic temperament.

Indie-electro rock not your thing? More in the mood for 1960s ballads and racism? At 8 p.m. they’ll be a screening of Hairspray, the new musical version with the cross-dressing John Travolta. Another film follows at 11 p.m. – Shadow of the Moon – the Best Documentary award winner at Sundance about the Apollo space mission.

Or, if it’s that perfect L.A. evening that reminds you why you stay out here battling traffic, just watch the live projections of Museum of Traffic across the Ahmanson and Hammer Buildings.

There’s also book signings, art making, screen printing (make your own shirt – just like American Apparel has homeless people do downtown) and tea and chocolate tasting. Just have a Tylenol PM/Valerian/Xanax cocktail ready to go at home as you’ll be twitching long after LACMA closes.

LACMA is located at 5905 Wilshire Blvd. in Los Angeles. Museum hours: Mon, Tue, Thu noon-8 p.m., Fri noon-9 p.m., Sat and Sun 11 a.m.-8 p.m., closed Wed. Price: FREE for these four days. For more information, call (323) 857-6000 or visit
