great Dreamlord, name some bands, please!
No prob.
Keep in mind some of these bands aren't "math-metal" as some like to call it. Some bands within the hardcore/metalcore scene that I feel are worth your time, but not necessarily better than Dillinger:
Botch - One of my favorites. Easily one of the more inovative bands in the scene. Makes Dillinger look about as innovative as another Gothenburg band.
Cave In - of course I'm only talking about their first two albums 'Beyond hypothermia' and 'Until Your Heart Stops'. The space rock that came after is pure camel crap.
Burnt by the Sun - They are good, but not as innovative as Dillinger. BbtS is more grinding though.
Coalesce - Basically the grand-fathers of the "noisecore" scene. Their stuff is fantastic. A good place to start is '0:12 Revolution....'
Converge - Probably the most brutal band in the scene today. I can only take them in doses, but they blow Dillinger outta there.
Deadguy - Another early band in the scene. Violent, angry, and creative.
Drowningman - Not near as chaotic as Dillinger. Much more melody in the music. 'Rock 'N Roll Killing Machine' is essential.
hopesfall - Not really comparable to Dillinger, but still worth your time. Emo mixed with hardcore.
Human Remains - Another early contender. Members went on to form Deadguy and Burnt by the Sun
Keelhaul - It's good, but not essential. Much slower and not nearly as nuts.
Knut - Tasty stuff here. If you like Dillinger, you'll like Knut
Kiss It Goodbye - Another one of my faves. Similar to Deadguy.
Some other bands related to the scenes mentioned above worth investigating are:
Neurosis
Today is the Day
Old Man Gloom
Isis
Mastodon
Cult of Luna
The Great Deceiver
and to a lesser extent...
Shadows Fall
Killswitch Engage
Fugazi
Life of Agony (old)
