Watch the Are We Sleeping? online guitar lesson by TrueFire from Play Rock Guitar 5: Lick Vocabulary
Are We Sleeping? - Lick 7 is a video guitar lesson presented by Angus Clark and is sourced from Play in the Style of David Gilmour.
There is a real edge and aggressiveness to Gilmour's playing that is belied by his somewhat reserved demeanor. This lick is pulling from this side of his personality. The use of the bridge pickup and level of distortion are important factors. As you'll also hear, specifically in the breakdown demonstration, during the first note of the lick, which is played on the first string, the second string is ringing against it which creates overtones that have a really cool sound. I encourage you to explore this "happy accident" when playing this lick.
