..told you i'm middle-aged and just a bit out of touch with whats going on..

my googling expedition has turned up this sub variant,
which is new to me..

"anti-folk"

More up middle finger than finger-in-your ear, Anti-Folk is folk with a punk attitude - none of yer fol-de-o-ray here, though acoustic guitars may be spotted alongside the electric ones and beards can indeed be found amongst some of the more hirsute band members (though not a fashion violation per-se and certainly not obligatory).
