Patti Smith

I'm not really a musician. I'm a performer, and I love rock n' roll. I've embraced rock n' roll because it encompasses all the things I'm interested in: poetry, revolution, sexuality, political activism - all of these things can be found in rock n' roll.

Frankly, as much as I love to improvise, it hasn't been difficult to stick to the script on 'Mad Men.' The writing is so precise, and the story so carefully crafted, that I don't think there's room - or need - for ad libbing. I could never come up with dialogue as lovely as these writers do, anyway.

Neil Young does throw in a major seven chord here and there, so if you're a new guitar player learning Neil Young songs, you'll learn some seven chords, and some different positions. Nothing too complicated, just enough to kind of open up your knowledge a little bit.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
