Watch the Over A Blues online guitar lesson by Rob Garland from The Guitarist's Pentathlon

In this example I'm playing Am pentatonic against an A7 blues and focus on leaving space, developing a theme, repeating it, embellishing it and play some licks out of minor pentatonic shape 3, one of the lesser used pentatonic positions, which can evoke Freddie King/Eric Clapton style phrasing.
