I have created and/or extended (from bare bones) a number of Wikipedia articles in the past, for folk (and other) based artists. To avoid controversy and the possibility of deletion, it is necessary to establish that the subject is "notable" by Wikipedia standards (I have on occasion fallen foul of this). Key to these are (1) "Has been the subject of multiple, non-trivial, published works appearing in sources that are reliable, not self-published, and are independent of the musician or ensemble itself", and/or (5) "Has released two or more albums on a major record label or on one of the more important indie labels (i.e., an independent label with a history of more than a few years, and with a roster of performers, many of whom are independently notable)", and/or (12 "Has been a featured subject of a substantial broadcast segment across a national radio or television network" (these are a subset of 12 criteria set out at https://en.wikipedia.org/wiki/Wikipedia:Notability_(music)). Most of the persons mentioned above would have no trouble meeting these criteria, I would say.

I am pretty busy at the moment on other tasks of a public service nature (science not music) but offer the above as a hint to others who may be interested. Note that there is plenty of scope for using Wikipedia as a "holding place" for relevant info providing that it can all be adequately sourced; or even a "bare bones" start can be useful for others to carry further.

Pages I have created or added to generally start off small (ish) but can grow into something more extensive. For an example small one, see https://en.wikipedia.org/wiki/Bob_Fox_(musician); for something longer (more of an essay / mini research project!) see e.g. https://en.wikipedia.org/wiki/The_Bushwhackers_(band) .

Once something is created, others may well jump in over time and extend or, sometimes, delete / change portions of your work, but them's the breaks, and it is best not to get too hung up on that unless one views the changes as definitely undesirable and is prepared to argue the toss.
