In its fourth year of existence, Air Jam has quickly become the grizzled veteran among this summer' numerous J-rock festivals. Debuting in 1997, this indie-rock/youth culture fest is perhaps Japan's leading omnibus event, bringing together bands from the punk, ska and hardcore scenes. Launched by Hi-Standard through their influential Pizza of Death indie label, Air Jam drew a crowd of some 30,000 moshers in its second year.

Topping the bill is, of course, Hi-Standard - a band whose brand of mellowcore music has previously earned them opening slots for fellow punk revivalists Green Day and Rancid. Also of interest are plenty of indie veterans: Bloodthirsty Butchers and Cocobat, digital hardcore trio Wrench, industrial thrashers The Mad Capsule Markets, and from the ska scene, Scafull King and Ska Flames. When you've had enough of the moshpit, check out the pro in-line skaters and skateboarders that will perform tricks to keep you amused. Plenty of skateboard and in-line skate makers will also be on hand, manning booths to show off their wares. Air Jam, in sum, provides the perfect opportunity to both check out an array of acts from Japan's vital indie scene, and to enjoy a day of fun in the sun around Tokyo Bay.

Air Jam 2000 takes place at Chiba Marine Stadium on August 26. See listings for details.
