Watch the Dirt to Dust: 8 online guitar lesson by Richard Gilewitz from Fingerstyle Narratives
Bars 84-102 are the entire slide section of the piece. Great care should be taken in a few slow ascent in the very first measure as you run up from fret 2 to 12 produces a much more dramatic effect. A metronome is almost necessary here to establish the proper amount of time allowed for this long ascent. The rest of the section can allow for periodic vibratos and shimmers with the slide as you see fit. This may vary from performance to performance.
