Can anyone recommend some progressive metal bands?

My favorite bands right now are Protest the Hero, Scale the Summit, Between the Buried and Me, Coheed and Cambria, and recently Irepress. I am pretty picky when it comes to music. I love protest's complexity and their vocal style. The only other bands with that level of technicality are like btbam, very heavy and usually no singing. If anyone has any bands with very complex riffing, cool changes and some singing, let me know
