By slash chords do you mean tritones, or whatever it is their called?
Code:
G ----5-
D ---4--
A --3---
E ------
'Gross chord in C'
If that's what you mean, the only thing I can't think of off the top of my head is a short section in the chorus of John Mayer's "3x5" where there's a pretty disonant chord, could be a tritone?
In my disonance-loving previous band, we fooled around in tritones all the time, but we weren't pop-rock, that's for sure.
And actually, if anyone knows the correct name for such a chord, what is it?
