They've had some trouble with vocalists in the past, and have gone through at least two or three before recording this album, but the one appearing in the current lineup (Spencer Sotelo) is an excellent choice. I'm enjoying this album pretty much every day and remain very excited about what the future brings for them.
"Djent" is apparently one of the genres that Periphery subscribes to, or so I think. I've never even heard of it until discovering them. I'm assuming it's a newer form of the really technical kind of metal that they play. They do have three guitarists, after all.
Check out one of the songs from the album, "Light":
My rating for Periphery's self-titled album: 4.5/5
(I took away .5 because of that really long and annoying part with the guy talking after "Icarus Lives". I had to edit that part out of my copy of the song, because I couldn't stand it after listening to it a few times. Other than that, this is a perfect album!)
