Scratch the surface of many a post punk fan of a certain age and they'll nearly all have too many Zappa albums in their collection - "betcha can't eat just one" etc. It is that Mothers - Beefheart - Pere Ubu - Sheffield / Manchester lineage. ZPZ were actually more like Sun Ra than Weather Report. Not too much noodling (Mr Vai not withstanding) but a whole lot of tightly arranged brain twisters. I was impressed and expected to hate it.
