Trying to figure out what song this is

[thelonewolf527]

Ok so I watch watching some of the HoganvsFlair Raw 2 Season mode streams (I'm sure at least some of you know what they are) and Caveman would play this one song to start off his shows. I cannot for the life of me figure out what song this is since there's no lyrics for the amount of the song that he plays. It sounds like it may be Dream Theater or something, but I don't have a clue.

Here's the part I'm talking about:

Does ANYONE know what song this is?
