"...a horrendous state of tunelessness..."

The New York Dolls' self-titled debut is blaring out of the iPod right now and I am reading a 1974 feature on the band from an old NME.
The feature, collected in a glam-rock history, recounts a Paris trip for David Johansen, Johnny Thunders, Sylvain Sylvain and the rest of the lads.
While the band sneers through such trashy numbers as, well, "Trash," on the iPod, I am reading about their 31-year-old gig at the Paris Olympia:
"Johnny looks about as well as his guitar is in tune. He staggers around the stage in obvious pain, beating his instrument into an ever-more horrendous state of tunelessness, which reaches its nadir on 'Vietnamese Baby,' when it becomes grotesque to listen to. On the next number, Thunders stops halfway, puts down his guitar and disappears behind the amps to throw up for five minutes."
That description is almost enough to make me start my own punk band, which is what plenty of people did after experiencing the anti-glamour of the Dolls.
