Halló, this is Iceland.
I have noticed that humans use this word from my people’s language to talk about a kind of tónlist that is often made by young humans who have many long hairs on their heads, and who like to drink brennivín, and do not take many showers.
It means "rock", and you say it almost in the same way. (And if you want to say “rock and roll”, it is very simple. You just say “rokk og ról”.)
The woman in the picture was called Sigríður. I do not know if she invented rokk, but I would not be surprised. When she was a young woman many young men liked her, and wrote songs and naughty poems about her.
Like many of the women who live on me, Sigríður had very strong opinions about how things should be. She built the house she is sitting in on this photo, and started a school for women in it.
And one hundred years later, the polite and well dressed people in FM Belfast, who also like to play music, and have very strong opinions about how things should be, played in a concert next door, that you can see here.
The photo-graph of Sigríður is from the Reykjavík Museum of Photography.
