This band is really really good in my opinion and I thought I should throw their name out there. They have a fast aggressive drive to them and have a reggae feel to a lot of the songs. There is also a progressive feel to a lot of their songs as there are a lot of cool jams and alternating meters. Their lyrics are also very good, I wanted to share some of them:

"I can't wait for the day
When I hear us all screaming,
HERE COMES THE REVOLUTION.
When every race color
And creed of militant human beings stand up
With fists together for substance and true meaning
Because right now we got our feet stuck in cement
We're too caught up in
A material status quo punishment
And one thing is for sure
And that's the sun will always set,
Darling you can bet our moon is quite the opposite
So baby take an axe to your makeup kit
Set ablaze the billboards and their advertisements
Love with all your hearts and never forget
How good it feels to be alive
And strive for your desire
Just cause you can't see
Your cage doesn't mean that you are free
When there are laws against nature
But its ok for you to be
Addicted to over the counter prescriptions
And magazines dictate all our human relations

I'm not buying, no I'm not giving in
To a culture that objectifies all of our women
I'm not buying, no I'm not consuming
The apathetic dribble on the news media's chin
I'm not buying, no I'm not giving in
The lies that are sold through textbooks to children
I'm not buying, no I'm not consuming
Cause the positive will
Always overcome the negative right"

"First comes the school
Then comes the job
Wife and two kids and a family car
We're all falling in line
And waiting to die
For what?
A plaque on the wall and another numeral
On a corporate statistic of a government chart
You know I don't need 
A read-out for the beat of my heart
You might as well get
A barcode tattooed on your arm
Cause convenience has strangled art in every form"

I highly recommend listening to "Falling Down The Mountain" (the jam towards the 3:00 mark is great) or "sell you beautiful" or "Decrescendo". Those are my favorite listed on the site. There isn't a band that has some prog influence that I've heard like this, so check it out.
