There certainly was a prog element in there. From concept style albums, leftfeild subject matter and some great odd time signatures.
In the middle section of Curfew on Black and White, which has a phrase repeated six times. The 2nd part of the fourth phrase has one extra beat in it.. why? WHY??
Oh and the drum pattern start of Peasant In The Big Sh*tty on a count of 9.
Also The Raven and The Gospel According To The Meninblack have some corking odd stuff going on.
I guess it was another of those bands with four differing talents that clicked. Jet's drum rhythms are rarely straight. Hugh's edgy spiky guitar. Dave's extraordinary keys and of course JJ's bass. Love them!
