For those of you who are not yet aware, Periphery helped to bring the style of metal known as "djent" into the mainstream. Their last full length featured many great songs such as "Icarus Lives" and "Jetpacks Was Yes!." Their latest effort has taken them to new heights. Periphery II peaked at #1 on the iTunes Rock charts and peaked at #8 on the overall iTunes charts. In my personal opinion they have also gone through an evolution as a band. Spencer Sotelo's vocals have very much improved since their debut album. I have often heard his vocals on Periphery II compared to Rody Walker of Protest The Hero.
