It's back. I'm hugely pleased to be able to announce another Postopolis, this time in Los Angeles, running from Tuesday, March 31, to Saturday, April 4, 2009. Two years after the first, at the Storefront for Art and Architecture in NYC and co-ordinated by BLDGBLOG, Subtopia, Inhabitat and City of Sound – here's a snapshot of that – we now have a different line-up of organisers/curators, covering a little bit more of the globe and an equally diverse set of interests:

• David Basulto from Plataforma Arquitectura and ArchDaily (Santiago, Chile)
• Jace Clayton from Mudd Up! (New York City, USA)
• Régine Debatty from we make money not art (Paris, France)
• Bryan Finoki from Subtopia (San Francisco, USA)
• Me from, well, here, City of Sound (Sydney, Australia)
• Geoff Manaugh from BLDGBLOG (San Francisco, USA)

We'll be taking the same broad brushstrokes approach to architecture and urbanism as last time and selecting a diverse set of SoCal-flavoured attractions for you. More details to follow, including the line-up of speakers and the precise details of the location. Polynodal LA makes picking the location a different challenge to NYC, but we're nearly there. Either way, it'll be free to the public, as easy to get to as LA makes it, and running from 1700 to 2300 each day.

And I hereby publicly promise to attempt to capture the proceedings as I did last time (though those who were there in New York will have noted I ran out of steam on the last day or so – eternal apologies to those with unfinished write-ups). Can't wait – the last time I visited LA it prompted more than a few thoughts. And if it's good enough for Reyner Banham, it's good enough for me.

Postopolis! LA is sponsored by the Storefront for Art and Architecture and ForYourArt, to whom we are very grateful, and it will be part of Los Angeles Art Weekend. Postopolis LA logo by Joe Alterio.
