The first Boston band in the top ten list proper (a hint that maybe there's a second? Third?), The Everyday Visuals incredibly catchy pop harmonies resonate a bit stronger in a world where Fleet Foxes can have such a massive impact. If you haven't heard TEV, the first time you listen, you're going to think to yourself "Wow, I could completely imagine these guys being out of the 60s and singing Beach Boys tunes."
And then I'll blow your mind and tell you how they've covered Pet Sounds in its entirety (I will pay you money if you can find me a recording of that).
While you are unblowing your mind, take a listen to "Florence Foster Jenkins." It'll make you feel better.
