Isis was really amazing. I missed their concert when they played at the Roskilde Festival a few years ago, so I was eager to finally see them. Isis are the founders of modern art metal, like a polished and more accessible version of Godflesh. The sometimes lengthy build-up in their songs may not always work when you hear them on your stereo at home, but when heard live they blow you away. Perhaps you just have to play them very loudly at home, and it'll work (to be tested). The concert was great and I hope to see Isis again soon.
