Jenny Lewis and Jonathan Rice collaborated on a rendition of Little Boxes for Season 2 (I believe) of Weeds. They collaborated very closely on Acid Tongue/are now a couple. At last year's Topanga Days festival, Jonathan Wilson, Jonathan Rice, and Gary Louris all performed together. These are some pictures I took at Topanga Days:
Gary Louris of the Jayhawks (I was SO star-struck when I saw him!)
Jonathan Wilson with Jonathan Rice (I don't remember the bassist's name on the right)
All of these people are amazing, yet somewhat underrated, musicians. Anyway, here's a great Jonathan Wilson video. It's a little long, but I recommend watching the whole thing:
I really like this video's Dionysus thing that starts around four minutes, really interesting. I definitely recommend checking out Jonathan Wilson's website, in addition to Whispertown2000 (I've been listening to their newest album Swim, which is pretty good), the Entrance Band, Golden Animals, and Spindrift. Not all from Laurel Canyon necessarily, but all good bands in the nouveau-psychedelia vein.
