?uest, i think 90 mins is ok, compares pretty well with other performances in my opinion, although i reckon i would be left maybe wanting more (depends on the energy and quality of the show). anyway, here's how you compare with a few others: (bear in mind that the club in bristol that most of the hip-hop goes on in imposes some kind of curfew, cos they allow anyone 14+ in, and this resulted in P.E. being thrown off stage one time)

Public Enemy: just over 2 hours
Jurassic 5: 1.5 hours
The Roots: 2 hours
Common: 2 hours

others i've seen (ozomatli, dilated...) have been at festivals, so i don't think that counts. by the way, on the north sea jazz festival website www.northseajazz.nl it says that you got an hour slot, but you are playing last on friday night, so you gonna rock it a little longer?
