Looking for some good metal bands?

I'm looking for some decent metal bands to listen to. I like the hardcore heavy riffs and stuff like Children of Bodom, Black Dahlia Murder, Lamb of God, Killswitch Engage etc. But those guys mainly scream. So I'm looking for some heavy metal bands with kick *** riffs and solos but with less screaming and some good vocal performances. Screaming here and there is alright but I want singing too. If anyone knows of some suggestions let me know!
