Trying to think of an artist with an accessible enough catalog that would have possibly had a huge influence on both of their lives... Radiohead seems like a strong choice, as mentioned many times. How about Beck? Huge artist, digestible catalog and probably liked by the Scotts. They could name it WTH,B? - What the Heck, Beck? And most likely not as influential to the Scotts, but a contender could be the Foo Fighters. Great songs, great rock and rolla music. And obviously...Are U Talking Foo To Me?
