A lot of people have one album that changes their lives, something that in some way alters everything after the first moment the hear it. 1999's Agaetis Byrjun is that album for a lot of people. Agaetis Byrjun (a good beginning), is actually Sigur Ros' second beginning. Three years previously they released their debut album, Von. After that the trio became a quartet and they evolved into something astounding. As suggested by a lyric from Agaetis Byrjun's title track, Sigur Ros had bigger ambitions after releasing Von.
