What are some good metal or heavy songs that will test an intermediate guitar player, looking for songs that will test a rhythm guitarist ?
Try these:
Trivium - Dying in Your Arms / Like Light to Flies
Machine Head - Aesthetics of Hate
Metallica - Master of Puppets
As I Lay Dying - The Darkest Nights / Morning Waits (easiest of these)

While they're not that hard if you know what you're doing, they'll test your playing nicely
ohai little sig.
Well i can play Master of Puppets and Aesthetics of Hate quite well but ill give the other 2 a go, thanks for the recs, anymore are welcome
