I agree with the sentiment that Tom's voice = Evergrey. Drummers can vary, and while I'm too lazy too look it up the drums on ISOT and RD are great, and Jonas Ekdahl has been a great drummer for Evergrey since then, bar Glorious Collision. However, Henrik Danhage is THE second guitarist. The twin guitar attack of Tom and Henrik, as well as their unique approaches to soloing are a huge part of Evergrey. I'm always amazed when watching the excellent 'A Night to Remember' DVD; Tom himself can shred like mad. Think about that for a minute: having that much vocal talent and being a proficient guitar soloist as well.
