"Metronomic music" is not that simple. For people who really love quantized beats
that technique represents an evolution and different form of listening.
Just like wanton compression, the technique can easily be used poorly. When Beato talks about quantization he talks about it like something that was added to the music, not something inherent to it. Jazz and its total explosion of the set composition represented something similar in the past, a kind of rhythmic and melodic freedom. Well, with electronic and now digital music, the freedom extends beyond the mechanical skill and constraints of the player's hand on the instrument.
Or maybe not, since you can easily consider the DAW an instrument itself, but operating in frozen time, completely open to manipulation.
I realize the music in question is rock and revolves around the idea of live people in live performance, but if you take rock which
really crossed into the sphere of computer music and absorbed its styles, what Beato says stops making sense, or makes sense only in a very limited sphere.
