The Beatles - Revolution from 1968's Double album The Beatles, aka 'The White Album'. Later the Stones would wrote a response with 'Street Fighting Man'. One of the first 'heavy metal' tracks. Lots of fuzz and gain on John and George's guitars.
The Beatles - I Call Your Name (2009 Stereo Remaster) "That was my song. When there was no Beatles and no group. I just had it around. It was my effort as a kind of blues originally, and then I wrote the middle eight just to stick it in the album when it came out years later. The first part had been written before Hamburg even. It was one of my first attempts at a song." John Lennon, 1980
