`Someone wrote: More recognizable, perhaps, is a type of what is generally called rock and roll called [folk rock]? or simply ``folk,`` which included performers such as [Joan Baez]?, Bob Dylan, Simon and Garfunkel, [The Mamas and the Papas]?, and many others.   I've tried to clarify this. ``Folk rock`` is used very specifically and is typically far more recognised by instrumentation than form. Many folk musicians of the 60s (Tom Paxton, Phil Ochs etc) sang new, topical material (which distinguished them from traditional folk musicians) but in the folk idiom (acoustic instruments, traditional arrangements and often traditional melodies.)  Re: the comment about ``marketers`` in the first paragraph. If language reflects common usage, what is now called ``folk music`` has as much right to the name as any other form. Gareth Owen  To the latter: fair enough, but does the first paragraph actually imply otherwise? LMS  I like the page in general but wonder if the following is unnecessarily cynical (implying, as it does, a financial rather than artistic incentive to change musical styles): :``Some of these performers, of which Joan Baez is an excellent example, began their commercial music careers performing traditional music in a traditional idiom, but soon transformed their style and accompaniment to suit popular tastes.``  Ya know, I agree, but I don't know how to change it right off. Anyone else want to give it a stab? LMS  The deletions are merely of things that seemed redundant. Additions may solve the problem of tone mentioned above. One bit of the original puzzles me, so I corrected the grammar but left it inbut what does ``unrecognizable to its source`` actually mean?  I like the new additionslots of good new information here. I added some more. The problem now is that the article is rambling and disorganized, and I am probably not the best person to organize and clarify it. BTW, using the word ``purist,`` without the quotes, makes it sound as if the authors of the article are not purists, which we don't want to imply. -) See neutral point of view. LMS  Perhaps someone who knows the facts -) could add in ``Skiffle`` music, from whence the Beatles sprang, which was evidently a British folk form in the 1950's.  Certainly the Beatles stole (er, utilised!) many folk forms in their music. `
