Many things of CONCRETE like a familiar, but so hatt`s You can hear nich. Raw and uncut. So should sound like a (real) newcomer band. Wartum should sound slick and perfect from the outset everything? The songs are of course recorded properly, but you can hear the raw hardness out clearly. In my opinion, CONCRETE is not as "perfect" styled like SOUL OF A NEW MACHINE or even later albums, but it's just harder. For earlier fearfactory and Death Metal fans the disc is just right. It is a pity that not got lyrics in the booklet are available from the previously unknown pieces, let alone "official" on the home page (which is also no longer the preserved is). But for that there ne good treatise on the creation of the album and why it was not published at that time. Only 4 points so because the acoustics is not the best sometimes. The songs sound sometimes a bit dull and overrides. But considering that it did not exist the technology as it is now 12 years ago, you will be able to get over this already. My tip: Listen and decide for yourself!
