I have to admit that I am of the latter mindset. And to those more mainstream music fans out there, I hope seeing performances by artists like The Avett Brothers, Janelle Monae, and Mumford & Sons will push you outside the bandwidth of your mix radio station.
And to address the upheaval of opinions about Arcade Fire... first, the main song the band performed is definitely not my personal favorite (and TV sound mixing definitely did NOT help). Also, just because you don't understand the style of their music, doesn't mean they aren't incredibly talented. Let's take modern art, for example... just because you don't understand the meaning of a Rothko painting, does not make his contribution to the art world any less important.
Please don't misunderstand... I own and enjoy pleeeeeenty of popular music. In fact, I find myself with the urge to admit that I, too, have "Bieber Fever" (ultra-hip NYC friends, disown me now). What can I say? The kid's got talent! Do some of his lyrics sound like they were written by a 15 year old? Yes, but they are supposed to. Are some of his hooks catchy as hell?? Of course! I've had "baby baby baby ohhhhh" stuck in my head for a good eight months now. On Sunday night, it was just nice to see that a more diverse group of musicians was represented in the performances and the award recipients.
So, let's hear it for, what some might call, a minor paradigm shift in the music industry this last Sunday night. I just hope it pushes some people to start exploring new music via websites such as Pandora or Last.fm. And if it's local artists you happen to discover... even. better.
