I have been listening to a lot of Dream Theater to get myself pumped for Saturday.
If you like DragonForce give Iced Earth a shot, similar sort of sound.
New bands (new for me at least) that I have been enjoying are Killswitch Engage and Children of Bodem.
Great thread, Metal is AWESOME.
Check out these guys too, a local Calgary metal band. They are AWESOME.
