Dehumanized was originally recorded by Symphony X on their 2011 album Iconoclast (you can listen to the Symphony X version here). It is about not giving in to the system despite being dehumanised by it. Dino and his band do an excellent cover of the song here with the vocals being more raw and having greater power than the original. The video is of Dino singing to the microphone while recording the vocals.
You can follow Dino on his Website, on Facebook, on Twitter, on ReverbNation, and on his YouTube channel. You can buy this music on iTunes.
