John Mayer stopped by The Late Show with Stephen Colbert on Thursday evening to deliver the live debut of “Wild Blue“, one of the laid-back singles from his hit album, Sob Rock. After releasing the new album in July, Mayer headed out on a massive, national stadium amphitheater tour. Of course, that tour was with his “other” band, Grateful Dead spinoff act Dead & Company, so the only album promo that took place onstage came by way of the guitarist’s neon Sob Rock merch. Now, following Dead & Company’s summer finale at Wrigley Field last weekend, John Mayer is back on the Sob Rock promo train with the latest iteration of his talented solo band, which he plans to take out on tour next year. Not one to do anything halfway, Mayer went above and beyond in crafting a stylistic and thematic aesthetic on Sob Rock, from the sound and feel of the material to the gleefully self-effacing, actively outdated marketing campaign he waged for months in the run-up to the release—both in real life and on TikTok. The album itself was an exercise capturing a bygone mood, Mayer explained in an interview with Apple Music‘s Zane Lowe when the album was released: “The idea of Sob Rock is that it might have been something that already happened, but when you go looking, it’s not. The idea of Sob Rock is to implant false memories into your brain. That’s what it did for me. … It’s out of my brain and it’s out of everyone’s shared Mandela effect. Can you have memories that never happened to you? Can you go back and synthesize a piece of work that’s so true to the era that when you hear it your brain goes ‘no, no, no, this exists?
