You're probably on a hiding to nothing if you've only got lesson time to work with, it's taken years of playing Coil to babies to brainwash my lot.
I'm in my 50's and I can well recall well meaning self styled 'cool' adults trying to get me into dad music like the Beatles way back in the 70's and to be honest someone hitting a tween with some Radiohead is likely to engender the same response...GTF! However...if you light a fire in just one or two kids all the indifference could be worth it and even then you might somehow make a difference to some kids years after they dismissed your Music to Watch Dads By suggestions.
I didn't like him much at the time but my music teacher at school was a fairly well known Scottish folkie and broadcaster called
Peter Mallan but in retrospect he let me use the music room record player at lunch time and in a roundabout way helped connect some music I liked back then like Eyeless in Gaza with folk and led to me buying up lots of folk records to try in the early 80's. He also introduced me to Child Ballads and Rouds and the lyrics really stayed with me. He was pretty/very shortbready but he directly pointed me at Dick Gaughan because he also did Jock O'Halzeldean and his antipathy to folk revival music like Pentagle or anything post psychedelic actually drove me towards them down the line, so even negatives can be positive.
He was also invoved in teaching me the Gay Gordons, the Dashing White Sergeant and The Circassian Circle (not an entry from the Hauntological music thread), which has been more use than I'd care to admit.
I very occasionally get talked into an extremely halfarsed and embarassing talk/presentation about folk with my sister's classes and now as then the kids (well roughly the third of the class that aren't falling asleep) like the bloodthirsty and intensely narrative nature of the songs, which they declare as 'very Game of Thrones'. It's fucking terrifying and I'd not fancy getting the young ones into anything even remotely my style without years of sublimimal training. I talk about how many of the stories are found in cultures all over the world and we try and come up with reasons why, be they travellers, certain universal fears and experiences and also how tales change through retelling.
I often have to work with young folk in their 20's and I'm often quite astonished at their musical conservatism, I used to try and Henry Higgins them but these days I just try and stay away from their music which seems more news and social media led than release led. To be honest I want to feel as bitter and alienated as old man Shadowplay did when he finally just told me to take the
family music centre to my room and never play any record I bought near the parental unit ever again, the day I came home with United by Throbbing Gristle in 1978. Up to that point I played everything I bought to them to a 'very nice dear' (translated as 'we hate this') but after TG there were no family listening parties.
One thing I notice is when someone dies I suddenly hear their music in the design offices, so if the likes of Macca were to die in the near future you might be quids in and I might have to find a quiet island for six months or forever...
Btw Imagine Dragons should be arrested under the trades descriptions act for being nothing like you'd imagine anything dragons would be connected with...unless we are talking Puff The Magic Dragons bedwetting instagram obsessed cousin.
I think I'd have to come in and speak to any teacher that tried it on with Wolf A Lice and any child of mine.
