Ihsahn (born October 10, 1975 as Vegard Sverre Tveitan) is a Norwegian composer, guitar, bass, keyboard player and vocalist. He is best known for his work with Norwegian black metal band Emperor. He has appeared in Thou Shalt Suffer, up until March 4, 2006, played in Peccatum with his wife Ihriel (real name Heidi S. Tveitan), and now devotes himself to his solo project, Ihsahn. In his very early releases, he went by the name Ygg. He is currently endorsed by Ibanez and Blackstar Amplification, as of February 11, 2012.
Ihsahn was supposed to tour Japan in May with Morbid Angel and The Haunted, but this tour was cancelled due to the disastrous earthquakes and floods Japan experienced in March, leading to the Fukushima nuclear powerplant meltdown.
Comments Ihsahn: "With the extreme unfortunate circumstances Japan has been exposed to this year, I am honored to get this second chance to go there and perform for my Japanese fans. Last night's show was a blast, and I'm looking forward to Nagoya and Osaka - see you all there!"
Ihsahn's backingband, progressive metallers Leprous, is opening the shows with a separate set.
