Which Kataklysm album should I get?

During their later era, Shadows And Dust was amazing. I like the Gladiator intro. It's fast paced. However, later on in the CD everything becomes slower and slower. Epic was good too. i like the track Era Of The merciless. Reminds me of At The Gates.
 
Arright guys, thanks a bunch. I'll be sure to pick up Shadows and Dust, Temple of Knowledge, Serenity and Fire, and maybe Epic.
 
You may want to try Victims of This Fallen world, it's much different, more experimental, but it's the start of the more modern-styled Kataklysm, so you may want to pick that up. Other than that, explore all of their albums really. Their older albums are by far superior but their newer stuff is by no means bad.
