Battle Circus (free music yo!)
 

They're a New Zealand band. They released a few singles over half a decade ago, an ep in 2007 (nearly 40 minutes long) and have just released their debut. It's mental.

It's free (though, you should pay :P) from their bandcamp Battle Circus

You can also stream their debut ep their + early singles (which used to be free, but is now $5).

I see similarities to Muse (only vocals) and a little bit of Pink Floyd. Maybe even Dream Theater (without being ****)

I think I prefer the EP, but Flying Machine is so so good...
