'Youngsters under 40.' There's your problem, encapsulated in that phrase. Personally, I find, as do others up the thread, the word 'youngsters' as patronising. Similarly, for me, words like 'folkie.' Maybe that's why a band has to call themselves 'The Young 'Uns,' which is cringemaking, in an attempt to fit in with the old folks? Or just clumsy. I'll be in London tomorrow, well tonight now, at a jazz gig, Cafe Oto in Dalston, which puts on an amazing variety of cutting edge musics. For me, best venue in town. Audience - a hell of a lot younger than me in the main, as they always are at this venue. Oh, 'youngsters.' Going to see Wadada Leo Smith, great American musician, supported by John Edwards on bass among others. He probably just fits into the straitjacket of 'youngster.' And is one of the best bass players in the world... As for improvised music/jazz, so for 'folk.' Plenty going on - if you're on the radar...
