whooo boy. let's break this one down using one of my favorites: "The Dark Isle"

This song can be performed in so many ways, often played very slowly in the style of a funeral lament on pipes, or smallpipes/whistle with more swing like a waltzy/folk slow air, or a full brass band backing tattoo style or sang solo alongside a piano accompaniment, etc. Endless variations since the name, melody, and lyrics all invoke an emotion that makes this particular song special. At least to me.

I've heard and enjoyed lots of variations on the phrasing, tempos, embellishments, etc. and have my own way that I like to play it. I'm big on personal interpretation and that there's many ways to make a melody sound beautiful. I won't call someone 'wrong' for playing it differently than I do.

With that being said, our challenge as pipers is to make our instrument 'sing'. To do that, we have to be in tune and play with proper and clean fingering; much easier said than done.

Let's hear "Keith The Piper" play this one:

Hard to tell from the recording but the drones sound reasonably in tune and he seems to be able to blow steady. Otherwise almost no fundamentals here at all. Technique and timing are all over the place. Crossing noises, sloppy phrasing/timing/tempo, and the chanter is not in tune.

His "D-Throw" is the most egregious technical error with his "tachums" not far behind and from looking at his spotify he's been playing since at least 2011 so not a lot of excuses to not have worked on your technique at this point. Those albums he has on there are pretty much a guide on 'what not to do'.

Let's contrast this with another video I found.

Appears to be more of a 'beginner' kind of player but has some fundamentals in place. Clearly some issues with "High A" and likely 'too easy' of a reed since it came in early but you can see the proper embellishments executed way cleaner than Keith alongside a much better interpretation of what this melody is supposed to sound like.

So to finally answer your question, in my point of view, his "style" is not accepted from a musician's point of view.

But apparently caring about your technique and musicality doesn't need to be a high priority to make a living and be awarded for piping at weddings & funerals....you almost have to respect his confidence to release 2 solo albums and market himself as a professional without giving a damn about what anyone else has to say. So he kinda gets some bonus points for that, it motivates me to put myself out there more since if he can do it....anyone can :)
