Jonsi (Jón Þór Birgisson) is an Icelandic singer and musician.
I’ll start with a sweet video of the song Hoppipolla sung by Jonsi when he was still part of the group Sigur Ross.
Here Jonsi is singing Sticks And Stones which was on the soundtrack of How To Train Your Dragon.
Go Do was off his first solo album.
Here he sings Boy Lilikoi.
