I've been listening to Zappa's One Size Fits All album since I was 2 years old. I would make my dad play it over and over. Now at the age of 40 I still listen to it on a regular basis. And the guitar solo in Inca Roads still remains for me, the most tastefully phrased guitar solo in existence. A few years ago I dreamed this solo, from beginning to end, in full HD audio. Just goes to show how good the brain is at retaining audio.
Starts at 1:58 or so....(amazing to see a Zappa album track that's remained on YouTube for so long, usually Gail has them taken down within seconds)
