Watch the Upstairs, Downstairs online guitar lesson by Robbie Laws from 30 Penta Sonic Blues Licks You MUST Know

A minor pentatonic box pattern #4.
You'll begin this lick with an ascending line, then quickly descend using a 1st position A minor arpeggio, followed by a pull-off and slide combination on the D string, finishing off at the open G string, which gives us the dominant 7th. Back down we go to the D string with a pull-off on the 1st fret to the open D. Hitting the A string with a 3rd, fret bend and finish on the open A string (home base).
