Unitron
A lot changed after Slipknot's debut Mate.Feed.Kill.Repeat., some possibly questionable lineup changes and change in sound. It doesn't sacrifice many of the experimental qualities of the debut though, rather switches things up. It's not as raw, and some of the influences are different, but it all works out. There's more electronic influences, not as many funk influences, the death metal elements pronounced in more specific ways like with the drumming and a few riffs here and there, as opposed to the more overall rawness and groove of death metal on the debut.
Some of the songs are reworked from songs on the debut, such as (Sic) being somewhat of a reworking of the song Slipknot, but instead of a noisy death metal track, it becomes a busy nu metal banger with blastbeats. Tattered and Torn and Only One were both on the debut, and honestly haven't been changed too much. They were screeching noise metal on the debut and they sound like that here as well.
The highlight of the album is easily Eyeless, intense nu metal blends with drum and bass perfectly, even before Psiheya did it more within a whole album context a few years later. Spit It Out is another electronic influenced song, with a mix of nu metal grooves, alt metal melodies, a short rap section, and short but effective breakbeats. Diluted, rap-heavy No Life, and the screeching Surfacing are other highlights.
If more funky and jazzy bass sounds better, go for the debut, if more noisy guitars and electronics does, go here.
