Left Hand Path and Clandestine are both brilliant death metal records. Classic stuff. Wolverine Blues is when they started the "death and roll" shtick and a lot of early fans got mad and quit liking them. Their loss though because that is a great album as well - it's just different.
People often get mad at me because I hate how Metallica changed. They accuse me of not wanting a band to change. Well Entombed is proof that I can accept change. I just can't accept suck. Entombed are excellent musicians that write great riffs and songs I like. Their last one, 2007's Serpent Saints is almost a return to their roots.
I hope they keep making records.
You should also hunt down their earlier demos and stuff from when they were called Nihilist - especially if you like the sound of the first 2 albums best.
