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   Ive 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 s 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 dont 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 dont 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 s  Certainly the Beatles stole er utilised many folk forms in their music
