I bought a copy of The Beatles' Revolver yesterday. I used to have this on vinyl when I was young, but hadn't heard it for almost fifteen years. Listening to the last track of the album, Tomorrow Never Knows, I was amazed at (a) just how far ahead of its time the song was, and (b) how much, thirty years later, the Chemical Brothers ripped it off for Setting Sun.

When you compare today's sequencing and sampling technology with what George Martin and The Beatles accomplished using analog equipment and tape loops, it's pretty amazing.
