I cannot even begin to describe Yo La Tengo's sound as it is so different. One song can be folksy, the next is filled with distorted guitar riffs then you can have a structured noisy chaos (oxymoron, why, yes it is). There are a lot of songs and I don't love them all but I love enough, also they do a lot of great covers. I seem to be partial to the songs Georgia Hubley sings.
There are actually two version of "Cherry Chapstick". The fast, upbeat version can be found on the album, And Then Nothing Turned Itself Inside-Out and the slow, mellow version on the EP, Today Is The Day! Both are Awesome!
Someone else's date in someone else's door
There's a girl with Cherry Chapstick on and nothing more
It's such a lurid pose and she seems this close
But not to me
I would hop around and try out all Yo La Tengo's albums. My favorites include: Fade, I Am Not Afraid Of You & I Will Beat Your Ass and Fakebook.
