While impressive how fast they could blast off a flurry of fast notes on their fretboard, the Eighties "shred movement" usually overlooked one tiny tidbit - the importance of songwriting. That's where Joe Satriani came in - utilizing single notes to play melodies that could have been supplied by a voice, or in the case of "Satch Boogie," blowing the roof off with some good old-fashioned blues-rock. As Satriani recounted to Guitar Player Magazine in 2007, "I started taking a ZZ Top/Van Halen-style-boogie, and injecting this warped two-handed tapping thing in the middle. But the devil on my shoulder urged me to do more, so I used pitch axis theory again. As a result, notes that make up the two-handed arpeggios in that section create some very odd tonalities that you wouldn't hear on a ZZ Top album." Before his solo career, Satch worked with Crowded House and Greg Kihn.
