Asgeir drumming for Ihsahn solo album

I heard that from the Emperor Interview at the Tinutus Radio Show on Wednesday, maybe I didn`t understand quite good what Ihsahn was saying about his solo album. English is not my main language I`m sorry if I provided wrong information.

They played a 3 song, fifteen minute set at the Scream Magazine show (the show Borknagar just played) to announce that they are headlining Wacken and Inferno.
