They're stuff is very repetitive but is fun to listen to when you're in the mood for that sort of thing. I saw them live when they were opening for Bury Your Dead and their show was awesome. They had random Family Guy samples thrown into their songs which was hilarious, lol.
Suicide Silence are awesum, their album The Cleansing blew me away so much, No Pity For A Coward is pretty epic. I can understand people when they say that sometimes it may be a little 'repetitive' in places but they are amazing to listen to. Their new album is fantastic, their lyrics have developed since the last album, but they are still keeping the same brutal sound. I read an interview from Mitch Lucker i think it was saying how they are classed as: 'deathcore' which to be fair is bs.
