Watch the Downstroke Slayer online guitar lesson by Chris Buono from 50 Metal Guitar Licks You MUST Know
A big part of your riffing technique will involve the jack-hammer like motion of continuous downstrokes not just on one string, but multiple strings, too. The dual guitar team of Kerry King and Jeff Hanneman are masters of this and have given the world of metal plenty of pulverizing examples. To begin getting that technique together check out this must know riff that's reminiscent of the epic breakdown in Slayer's "Raining Blood" from the closely named Reign in Blood album--a Slayer classic. In addition to the downstroke treatment, the real must-know attribute is the palm muted low-E string thud that's played on every downbeat.
