A question I often ponder, and which cannot really be answered, but I'm keen to hear some thoughts. Here is my opinion:
Drums - Steve Flynn (Athiest)
Bass Guitar - Tony Choy (Cynic, Athiest, Pestilence)
Synths (if I had to have them) - Isahn (Emperor, Thou Shalt Suffer, Peccatum)
Guitars - Chuck Schuldiner (Death, Control Denied)
Guitars & Vocals - Mikael Ackerfeldt (Opeth)
