Even before debuting with the remarkable "Remission", Mastodon released this EP titled "Lifesblood" in 2000. Are you familiar with the sounds of their debut album? Well, here too, Mastodon works hard to create chaos, but without melodic or elaborate elements as would be present in their later work: in this quarter of an hour of music, it's just pounding, and it only takes the first track "Shadows That Move" to make that clear.
However, this EP presents some curiosities: it is full of samples. Before the start of the first track, you can hear Jack Nicholson's voice from the wonderful film "One Flew Over the Cuckoo's Nest; in the intros to "We Built This Come Death" and "Battle At Sea", you can hear clips from the Nuremberg Trials, and finally, in "Hail To Fire", the sample is taken from the film "The Dancin' Outlaw". The only track without a sample is my favorite, which is "Welcoming War", featuring a frenzied riff that's not bad at all.
In conclusion, if you already know and love early Mastodon, this EP certainly won't offer you anything new; whereas, for those who don't know this band and want to start from the beginning (as I did), it will offer a quarter of an hour of pounding music.
