VÆB (pron.: VIBE) are the brothers Matthias David Matthiasson (20) and Halfdan Helgi Matthiasson (21), who have been involved in music since a young age and come from a truly musical family. Their father, Matthias, is an organist, saxophone teacher and choir director and their mother, Aslaug, is a singer and singing teacher. The older brother, Halfdan, has a twin sister, but together the brothers have four siblings. They started learning instruments at an early age, Halfdan on drums and Matthias on trumpet. The brothers have sung a lot since childhood, and in 2015 Halfdan won the popular children's television singing competition in Iceland, The Christmas Star, at the age of 12.

In 2022, the brothers formed the band VÆB after posting a video on TikTok with a "joke-song" that attracted so much attention on social media that they decided to release it on Spotify. They released a few more songs, but in 2023 they met songwriter and producer Ingi Bauer. The brothers participated in the Söngvakeppnin (Icelandic pre-selection for Eurovision) last year with the song Bíómynd (A Movie) and finished in 4th place. They were a hit in the competition and became nationally famous overnight and held many concerts around the country as a result. They then decided to try again at the Söngvakeppnin this year and won the competition by a landslide, both in the public and jury vote, with the song RÓA (ROW). The brothers have said that the song is about moving forward in life. No matter what is going on in the turbulent sea of life, you have to keep rowing and never give up. The song RÓA reached the finals of this year's Eurovision Song Contest and has been a big hit. It has now been played over 17 million times on Spotify. The brothers are booked in Iceland all summer and will be touring Europe in early 2026.
