The freeway appears regularly in L.A. art — works by Ed Ruscha, Dennis Hopper and Catherine Opie come to mind — but rarely does art grace the Southland’s concrete corridors. There is graffiti, of course, and a smattering of decaying murals, but for the most part, the freeway is an artistic wasteland.

Until now. Coming to select rush hour traffic jams this summer: “Superclogger,” a mobile puppet theater by Los Angeles artist Joel Kyack. Accompanied by fellow artist Michael Hayden, Kyack performs shows out of the back of his nondescript white pickup truck for anyone who happens to be driving behind it.
