My intro to Ihsahn came with his "Eremita" album, and I was really blown away with the textures. Definitely a top 10 fave album for me now.
But right now:
I just received my copy of "After" by Ihsahn, and it is a great album. Very nicely produced. Sounds great if you have a good speaker system. I think I will order Eremita next on amazon.
...and Painkiller.....what's not to say about the Painkilllaaahhhh! lol....The drum intro is still badarse after all these years. I'm running one of my Cerwin Vega Stroker 15's in a 5 ft³ ported box in my house, and the drums sound killer on it at full blast.
