Back in Sweet 16 we first felt the power of double stops and man is it invigorating. Those nasty two-note bullets sound ferociously good when fired properly. The same holds true here in this final chorus of Hamburger Meat where you'll bounce a pair of major 3rds off a 16th fret, 4th string root for the first eight bars. And, you're not done there. Bars 9-10 continue the onslaught with chromatically descending 3rds only to be followed by some pioneering rock n roll lickage in bars 11-12. Though bars 13-14 back off on the dyadic muscle it's no less potent if you play with the aforementioned attitude. So roll up yer sleeves and getter done!
