It occurs to me as I read this discussion that different styles/genres/generations of music carry with them some very unique recipes. One can't really alter ingredients arbitrarily without affecting the final product. Today the world is full of young musicians who need to posess a lot of tech stuff to recreate the music that means something to them. It may seem logical to them to consider more and better tech to be a blessing. But that's
their recipe.
In the late '70's I was getting tired of the direction pop/rock music was going and started checking out Chicago Blues. Less slick, less technology for sure. More to my liking at the time. A different recipe. I like music that has more room for the humanity of the musicians and singers to shine through. I would rather have a drummer who felt free to trust himself and feel the songs. It doesn't mean I'm right. But it does fit the recipes I like to cook with. I have played with time-challenged drummers. I hate it. So I'm not saying you want to turn the reins over to an erratic drummer. Just the same, there is a loss of feel introduced into some forms of music by the rigid adherence to metronomic time. As George Martin once said of the Beatles, their time wasn't always perfect, but it was "wrong the right way." (Paraphrased, so Google won't be your friend here.)
Here's an example of a song that would probably not be improved if played to a click. BPM is radically different betweeen verse and chorus, yet the song is served IMHO. Idiosyncrasy isn't always a bad thing in my world.
