The band has toured extensively, including performances in Denmark, Germany, Norway, Luxemburg and at the famous Cavern Club in Liverpool, England where The Beatles played in the early 1960s.

Magni was virtually unknown outside of Iceland until he competed on the U.S.-produced music television show, Rock Star: Supernova, in the summer of 2006 where he earned himself the nickname of "Ice-Man".

Magni made it to the show's season finale, finishing fourth, behind Dilana (second) and Toby Rand (third), and new Rock Star Supernova frontman Lukas Rossi.

A homecoming celebration took place at Smáralind on 17 September 2006, when Magni returned to Iceland after his three-month stint with the CBS show.

Magni, along with one of his brothers, presents the Bræðslan festival near his hometown of Borgarfjörður Eystri annually during the last weekend of July.

Iceland's President and First Lady presented Bræðslan with the 2010 Eyrarrós award for excellence in culture in a rural area.

Magni has also occasionally performed in the U.S. and Canada since his stint on Rock Star: Supernova, including several shows as a duo with Dilana.

Magni has competed before in Söngvakeppni Sjónvarpsins, performing the song "Flottur karl, Sæmi rokk," which qualified for the final as a wild card in 2006.

In 2011 Magni competed in Söngvakeppni Sjónvarpsins for the third time with the song "Ég trúi á betra líf".

[5] Magni has a solo album in English that was originally released on CD in Iceland on 3 August 2007 and as a digital download elsewhere in the world on 9 October 2007.
