For those unaccustomed to hearing pure intervals it can sound like a high-gloss "sheen" that gives an unreal quality to the music. In a way it becomes "too perfect" and unnatural to those who are used to hearing the equal temperament that most western music is recorded in. I hear it a lot in some acapella vocal groups and I often find the sound off-putting and it somehow feels a little corny to me.
Still, his virtuosity allows him to do things that very few people are capable of conceiving, attempting, and doing. We're lucky to have him in the mix.
Billy Corgan of The Smashing Pumpkins is an example of someone who has both the talent and the taste for making great music in my opinion. There's a really old video of him shredding like a madman [1] completely off the dome which shows he has very good command of his guitar. He's not in the same sphere as Jacob Collier mind you but here me out. If you compare that video with the music he wrote in the pumpkins, it is very restrained. He knew when to exercise the full range of his skills and when to dial it back. Having learned a lot of pumpkins songs on guitar, it is clear to me that he favoured what sounded better and was more impactful over what appeared skillful.
There's another video of him in 2012 [2] where he talks about influential music coming from the internet and people in their desktop studios, not from guys with guitars trying to make it big. Beyond his talent he had a very keen eye for how music was evolving. Having talent is one thing, being able to contextualise your work, and others work accurately in the arena of the world is a quality that very few people possess and in my opinion is required for producing truly influential and impactful work.
That's a great clip. You might enjoy some of what people have been doing with their desktop studios and guitars in the last few years. Two that immediately come to mind are Tim Henson [1] (already pretty well-known in the guitar world as part of Polyphia) and Manuel Gardner-Fernandes [2].
Probably quite out there (doom/drone/stoner) for most people but his music has always struck me as incredibly from the heart and not some noodling to impress others.
archaic or arcane?
You can also use arcane.
Compare his stuff to the work of Kamasi Washington, Mary Halvorson's groups, or Shabaka Hutchings, or Christian Scott aTunde Adjuah, and you hear an enormous difference in the sheer craft of songwriting, emotional dynamics, and storytelling through their instruments.
He's clearly a virtuoso at a kind of playing the instrument, and he's extremely good at explaining music theory and concepts, which is a rather archaic and unique language all its own, but I don't think he's quite there yet for songwriting.
