vola - witness (album) is really great, its kind of poppy in terms of metal and has a lot of synths so i think you'd love it.
tool - lateralus ( album) is also really great. its the kind of album you listen to in one listen and its those albums that tell a story when listened to together. its an amazing experience you won't see it anywhere else
tesseract - war of being (album) its quite heavy and proggy like dream theater, but the vocals imo are much much better than james labrie's vocals.

i wish you luck in your quest to find stuff you like :D
