So basically I've been getting into quite a bit of progressive metal and was inspired by The Corporation's topic a little while back to make another one right now
Animals as Leaders
These guys are amazing, they have a very nice blend of progressive jazz metal along with some Djent elements. The use of complicated and very dynamic time scales along with all the 8 string guitars you could want makes for great instrumental songs, both heavy and calm. I haven't even listened to all of their songs yet I would say they are currently one of my favorite bands as of now.
Periphery isn't quite as innovative as AAL, but they are still quite good to listen to, especially if you want more heavier stuff. They have a vocalist who screams every so often, but they also have released the instrumental parts of pretty much of all of their songs too. I haven't listened to them as much as AAL, but I recommend them to.
There's also a few others that are good such as TessarcT, and a few others I can't name right now cause I'm tired. Also, if you want to try a band with a Djent tone and rapping, try Hactivist.
