Watch the Crossroads: Ex. 2a online guitar lesson by Andy Aledort from Kings of Rock & Roll Vol. 5: Eric Clapton
The solo Eric Clapton recorded for Cream's live version of "Crossroads," inspired by Delta blues master Robert Johnson's "Crossroad Blues" and featured on Cream's brilliant double album Wheels of Fire, remains one of the most essential blues/rock solos of all time - a must-learn for any aspiring blues or rock guitarist. This excerpt is played along the lines of Eric's first 12-bar solo, and alternates between A major pentatonic (A B C# E F#) and A minor pentatonic (A C D E G). The first two bars are based on A major pentatonic and then the lines shift seamlessly into A minor pentatonic.
