What do ZZ Top, Florida Georgia Line, Luke Bryan and Jason Derulo have in common? Absolutely nothing… until last night. CMT prides itself on pushing the envelope with genre-defying, odd-couple pairings. But the network might have jumped the shark by opening the show with a live mashup of the three aforementioned artists. ZZ Top kicked off the debacle with an abridged take on their Texas roadhouse classic "La Grange," which was preempted by FGL bros Brian Kelley and Tyler Hubbard (along with Bryan) trampolining out of the stage with freeze-frame precision (cued to explosions, of course), then launching into their wholly sonically disparate "Cruise" sequel, "This Is How We Roll." That makes about as much sense as Floridian neo R&B auteur Derulo cannonballing to the stage with back-up dancers in tow and hyping the crowd with the Middle Eastern-sax-melody-boasting, country-as-a-sky-scraper trap of his 2 Chainz collab "Talk Dirty" — which is exactly what happened next. Derulo's choreographed dancers were off the hook. Kelley and Hubbard doing the windshield wipers dance while Bryan slithered and thrust his hips, not so much.
