• Only Sparks could look at the great waterways of the world - the Danube, the Seine, the Nile - and decide that Los Angeles's clogged artery of concrete and brake lights deserved a place among them. "I-405 Rules," from their 28th album MAD!, is an ode not to a river but to the freeway, that strange LA substitute for natural beauty.
  
  "In Los Angeles we don't have an iconic river we can brag about," Russell Mael told The Sun. "But the I-405 Freeway takes on its own beauty, especially at night."
• It's a very Sparks conceit: reimagine the monotonous as majestic. Where other cities have rivers that inspire poetry, LA has the 405, and Sparks give it a hymn fit for the Rhine. The irony, of course, is that most people's experience of this "river" is not gliding serenely along it but sitting motionless, bumper to bumper. Yet, from a certain angle - say, the Getty Center at dusk - the endless stream of red taillights does resemble a sea, and Sparks lean into that grandeur with a sound that's deliberately "overly dramatic for the subject matter," as Russell put it to Apple Music.
• The song joins a tradition of I-405 shoutouts in pop music. Halsey once used the freeway as a symbol of restless escape in "Drive"; Kendrick Lamar plotted teenage mischief on it in "The Art of Peer Pressure"; and Beyoncé, in "II Most Wanted," turned the road into the backdrop for a modern outlaw romance. Sparks, true to form, take a different route: not escapism, but elevation, declaring the I-405 itself a thing worth revering.
