I seen Kamelot right down front and center at the Algora in Cleveland after the release of The Black Halo. The drama of Khan's singing and his delivery was just staggering. I was literally drained from the experience. For me, progressive metal usually starts first and foremost with great guitar - Petrucci, Loomis, Romeo, Micheal Couts, Lofstad, Brick Williams, etc. But with Kamelot, it was Khan that always first captured my attention. (That is not to say that Thomas is not a great and captivating guitarist - he most definitely is!). Can Kamelot attain the same greatness without Khan? I hope so and I think that it is possible. As many here have pointed out, Thomas really sets the direction for the band and I am glad that they are taking their time to find a new singer. I do have to say that even if they exceed The Black Halo, Kamelot will not be the same without Khan. Better - possibly. The same -no.
I respect Khan's decision. Hell, it's his life. I thank him for all that he has given us. And, I hold out hope that we will hear from him again.
