What are some good bands?

i like bands like korn,slipknot,powerman 5000,linkin park. but, im looking for some good heavy rock/metal like slipknot, but without the vocals/lyrics. something like powerglove... thats about the only thing i like so far. joe satriani, and ynwgie are okay but not really what i am looking for. dont really like pelican,red sparrows, bottled science. i want that fast pace rock music like powerglove has... there are some bands like deathklok that sounds awesome but it would sound better without the vocal. im not really into the deep yelling to the point where it sounds like theyre choking something or have really bad flem.if you know any good bands, please comment
