Tourist,
Not much inside info on this band other than they are an American Death Metal band who write lyrically around a violent and bloody construct. Think the most bloody and violent gore movie and you'll have the idea. As for going to see them? Look at the lyric content and decide for yourself but it's just a gimmick and one that never worked for me. Let me know if you decide to go see them and what you think. Are they playing at the Orange Peel?
DS,
I don't mind the death vox or death growls as it's a form of instrumentation not unlike the heavily dissorted guitar. First time I heard death growls, my reaction was much like your's but it was the Swedish Death/Black metal band Opeth who uses a progressive rock underpinning that got me to take the vocal concept with some serious consideration. Consider it almost in a type of point/counterpoint or a dark/light kinda thing.
Michael Akerfelt, Opeth's vocalist uses a mix of clean and death vox and the band even did a purely clean vocals album called Damnation that really opened the door for them among the fans in the Progressive Rock world. Steven Wilson of Porcupine Tree produced 3 of Opeth's albums including their breakout album in Blackwater Park. One song from Blackwater Park, titled Bleak has an almost Zepplenish feel to it like Kashmir in that it uses this Middle Eastern vibe or rift to it but in a head banging tempo. Vocals are a mix of death vox and clean.
Here's a live version of Bleak.

Now for contrast using clean vox and a very melodic song off Damnation called Windowpane.

Windowpane was the song that got me to consider the band as a whole. Their latest album, now about 2 years old entitled Watershed was heavily influenced by Akerfelt listening to a lot of 1960's Zombies with Rod Argent as well as Frank Sinatra and his album The Drift. Think about a death metal album influenced by the Zombies and Sinatra. When you listen to Watershed you can hear those influences for sure and that's what I like about Opeth as they aren't the typical one dimensional metal band. Most death metal bands I tend to become bored with but Opeth's diverse catalog tends to really hold my interest.
