Check out this great video of Bill Watrous playing, “Nancy with the Laughing Face.” It blows my mind how smooth he sounds, and has everything to do with his slide technique.
Watch how fast he arrives on each note playing the melody. The next ingredient is what “warms it up.” He then applies his wonderful, individualistic slide vibrato, and back lightning fast to the next note.
The personnel is stellar, and offer a profound performance. Enjoy!
