Well, I don't have any problem keeping them apart, and wouldn't stick the great solo in Fermented Offal Discharge in To Breathe In A Casket. Personally, I think they're the best thing to be released on CD since the Death and Atheist stuff of around 1990. Like Ron, Muhammed has one major thing going for him: he doesn't sound like the umpteenth GIT graduate.
Muhammed is, if I understand correctly, self-taught, thinks Ron is a god (as do I), and took his inspiration from Yngwie and Chuck - both of which I think I can rather easily identify in his guitar playing, even if he's combined them into his own style. He stands out in Death Metal due to his technical capabilities, song writing with great riffs and flow to the compositions and the combination of dirty, aggressive rythms with great melodic fills on both bass and guitar, and an easily identifiable style. The way he combines the sweeped arpeggios with slower parts and speed picking gives me goosebumps from time to time (especially the Fermented solo, but there are other examples).
I love it! And I hope he'll have some new twists to add to the new album after experimenting with a 7-string, which Muhammed mentioned he was using for composing the new stuff. I hope his new addition to the band (Sami Raatikainen replaced Christian Muenzner - hope I got those names right...) will add a new angle to the new album, too. Recording is tentatively planned for end of this year, and that and Blotted are the two main releases I'm keeping my fingers crossed for, now that Mathematics doesn't seem likely to be finishes any time soon, or perhaps even ever...
