I'm not much for classical music, but I do appreciate it and its influence on other genres over the years.
This particular 'piece' is just.....weird.
I like its simplicity and how it probably is trying to say something fancy about the power of performed music or something like that, but it's just...weird to call this a 'piece' and be all excited about how powerful it is or whatever. I think it's unique, at least.
I saw Andrew W.K. perform last week at the Largo in LA with a string quartet, and he and the band attempted their own version of 4'33"....check it out:
Pretty funny, what with all the kids on stage confused about what was going on....
so yeah, 4'33" is interesting, but I'm not so sure I "get" it.
