Awesome cover. Bobby's guitar solo on that song is definitely a favorite. IMHO, one of the best throughout the Death discography.
I have the the 2 Death tab books, the one published by Guitar World and the one by Relapse Records. Every now and then, I look at them, flipping through the pages and thinking about covering some of the songs. But the Obscura songs that I'm covering (from the tab books) take up a lot of time.
