Watch the Hoochie Mama: Lead 2 online guitar lesson by Andy Aledort from Jam Night Vol. 3
Albert King's vocal-like phrasing works perfectly when balancing lines against a heavy repeated riff like this one, so i stick with lines based on A minor pentatonic (A C D E G) that are fingerpicked, snapping the strings against the fretboard in an aggressive way in order to emulate the "Albert" sound. I begin with a two-step pre-bend--very Albert--and then I gradually release the bend to whole and half step bends in a vocal-like manner. After the initial series of bends and releases, i move up to A minor pentatonic as played in 13th position so that i can play higher melodies while staying on the G and B strings primarily. Be sure to listen very closely while bending so that each pitch is perfectly in tune. When the five chord, E drops in, I switch to the Johnny Winter-like tremolo picked thirds on the top two strings, brushing across the strings while picking as fast as I can.
