Three initials. Umpteen members. And timeless songs the kids love. That’s right; TTB were on TV on Wednesday night! (What? Who do did you think I meant?) And not only did the Tedeschi Trucks Band deliver a smokin’ performance of Shame on Jimmy Kimmel Live’s outdoor stage; they also conjured up another 20-plus minutes of soul-powered blues-rock jammin’ (hope you like jammin’ too) for the YouTube. But even that’s not all — the TV-music gods were in a truly rockin’ mood on this night, dishing up solid performances all around the dial. Canada’s own Pkew Pkew Pkew tore through I Don’t Matter at All on Late Night with Seth Meyers, channelling the post-punk fury of SST’s heyday. Icelandic popsters Of Monsters and Men turned up the volume with the fittingly aggressive ’90s-style alt-rock of Alligator on The Tonight Show Starring Jimmy Fallon. Mr. Jim also brought out The Who’s Roger Daltrey and Pete Townshend to play Won’t Get Fooled Again on classroom instruments — with Pete obligingly smashing his toy ukulele at the end. (Good thing none of The Roots smoked any of the weed before Roger’s performance.) After all that energy, some mellow fare is just what the doctor ordered — and just what alt-country singer-songwriter Rayland Baxter offered on Last Call With Carson Daly with his songs Everything to Me and Hey Larocco. Finally, for those who want to see flash-in-the-pan popsters desperately trying to come off as the next Beatles, K-Pop boy band BTS showed up on The Late Show With Stephen Colbert to dance their way through one of their instantly forgettable singles. Oh wait, now I get it.
