This is by far my favorite band, but it is also not the only thing I listen to. When I first heard this band (FCPREMIX) I didn’t like it at all, but after listening to that ten times I was instantly (sort of) obsessed with the band. I would suggest listening to the songs in a certain order, gradually let yourself into the screaming.
FCPREMIX->
“You got a Deathwish Johnny Truant?”->
Act One, Scene One->
Whacko Jacko->
Then you’re pretty much into it enough to not be shocked.
