alt Hacker NewsAgree. What is interesting in a band situation is when one human does something another human doesn't expect, whether by accident or just trying something different. This cannot happen with solo artists and laptops.
This is why Angine De Poitrine is vastly more interesting than Tame Impala to me.
To play devil's advocate here, there are plenty of examples where computers (or other kinds of non-human systems) create music in a way which human listeners don't expect. Anyone who's ever played with a drum machine knows you can click a random pattern in and accidentally make something that sounds really good.
