Circling back to thank you for this posting this:
1. I love how both the Byrds and Television layered their guitars. "Turn, Turn, Turn" and "Marquee Moon" (& that the whole album, actually) will never get old for me -- they're both just as thrilling as the first day I heard them.
2. I love that Nels Cline makes mistakes and sometimes can't wrap his hands around a riff. Hugely encouraging for this fat-fingered guitarist.
Very glad you enjoyed it, i've watched it a few times. His joy and love of what he's hearing in the music is infectious. Impressed how he sings one guitar part while playing the other, any of his demo's, interviews are fun to watch.
Another series i've recently come across is on the Noisey channel, Guitar Moves with Matt Sweeney interviewing and playing with various guitarists discussing licks and influences, quite short but always fun. Recent ones i've watched are with Keith Richards on the first song he learned from his grandfather, James Williamson talking/demoing Raw Power songs, Josh Homme and the host sweating buckets at Homme 's house, J. Mascis, 30 years playing and i've just learned how to palm mute... like you noted with Nels Cline, they make mistakes, they struggle, they love playing guitar. Guitars, just tools of the trade.
