Well, even considering that aspect, I've found that there are DeeJays and there are DeeJays.
Some of the youngsters seem to exhibit a lot more talent at the game than others, just like when Guitar Playing is the objective.
Have enjoyed a local CoolJazz ensemble that mixes it up with Drums, Bass, E Guitars, Sax, Singer, Percussionist - and a DJ who does the record scratching thing along with sampling and must say that their act works well.
This kid is doing a lot more than just pushing buttons. Changing vinyl, finding the exact spot on the recording desired, cueing it up in earphones and then placing it n just the exact spot of the performance kept me watching to see what neat little thing he'd come up with next.
I also had a bit of fun with it, as he was sometimes cueing bits off of old jazz records that I thought I really knew from listening and practicing, but had never really heard perhaps but one note or phrase taken out of context like that. Miles. Trane. Diz. etc.
These kids are working up their THING, and while it may not be my cuppa tea exactly, I recognize good if not strong performance. And if they keep at it, that good may just end up being strong.
When confronted by musicians from my age group knocking that which a younger generation is doing with music, I like to think back to my Dad's viewpoint about the guitar, be it acoustic or electric. He always told me to stick with the "real" instruments I already was learning to play, the Trumpet and the Piano. No matter how many billions of dollars people made with guitars, he was adamant that the guitar was merely going to prove to be a passing "fad". He took that and other prejudicial notions to his grave. I've tried to not fall prey to such illogical perceptions. With varying degrees of success.
