death metal bands

I'm a fan of Ouroboros. The guitar work is fantastic. I don't know if they employ prominent guitar solo work. Their signature song "Sanctuary" opens up with a lengthy guitar tapping sequence. Do you consider that a solo?
 
My Dying Bride has excellent guitar work and very few solos. They purposely pace their rhythms down to a funeral dirge, with sporadic lapses into frenetic passages. Often, the drums are the lead instrument, especially in the older stuff, dominated by Rick Miah.

Hamish, one of the co-guitarists, has degrees in music and says, "knowing the rules helps me know how to break them".

Most people consider them a Doom band, but NOBODY does Death vocals better than Aaron, especially in the early stuff.
