I saw Sigur Rós live. Didn't think I would enjoy it one bit, as Icelandic music is not anything I was familiar with. But holy hell, it was hypnotic music. I became a fan overnight.
I was in an independent record store around 2004.
I was perusing some jazz, some punk and a really cute alternative chick starts chatting me up.
We talk about music and she says to me: "Have you heard of Sigur Ros?"
Me: "No, are they good? What are they like?"
Her: "They absolutely rock!! They are nothing like you have heard before."
She was right on the second part, but not on the first. I would hardly say that they "rock". I am a big fan, however.
I was with a girl in that shop that I have been friends with since I was 2 years old. Every time she sees me (which isn't very often these days) she says: "Yo, Sigur Ros rocks!!!" while holding up the rock fingers.
