Well it does save time on sound checks.. but i like to watch something before i play personally not some bloke with a laptop! In the 90,s MK2,s they used to put a punk band or rock,a,billy band on to keep me happy*
At least DJs are easier to chuck bottles at if they suck...I kid, I kid. You know how I feel about people throwing Hong Kong Phoey at the stage...more than ever after I had to dry clean the suit I wore to the April Shells show after 15 minutes in the photographer's pit!
I would really rather a good rockabilly band go onstage than see another Scooby Doo DJ. Maybe I'm getting old, maybe it's just 'cause I spend so much time photographing at clubs...but I miss seeing MUSIC played instead of records.
