Björk has been making music since she was a child. She released her first album when she was 11 years old. Her music doesn't sound like anyone else - she uses unusual instruments (sometimes she sings with the noises of the wind), wears amazing handmade clothes, and her songs can be wild, quiet, or both at once.
Sigur Rós are a band who sometimes sing in a language they invented themselves. They call it 'Hopelandic' - it has no real meaning, but it sounds beautiful, like singing made of feelings. Their songs are slow and dreamy, often building up from a soft whisper to a huge sweep of sound that feels like watching a glacier melt in sunshine.
Lots of musicians from outside Iceland visit to make music, because Iceland is so quiet and the landscape is so dramatic. The country has its own music festival called Iceland Airwaves, held in Reykjavík (Iceland's capital) every November. Concerts happen in old churches, swimming pools, bookshops and even lighthouses.
Music is a part of growing up in Iceland. Lots of children learn an instrument or sing in a choir. Even small villages often have a community choir that meets each week. Icelanders sometimes say they sing through the long winter to keep the dark away.
