I like them. I am not a mega zeppelin geek so what should I listen to?
As I learn more and more on the guitar I keep coming across the same things.
I'll learn one solo and think oh slash or Eddie Van Halen nicked that lick from Jimmy page who nicked that lick from chuck berry or whoever. In crossroads clapton plays a certain lick that I heard on a BB king track.
Not that it's a big secret. It's obvious but when you breakdown these things even closer it's even more interesting.
There are plenty of famous solos that have little bits from here and there from other places. I will become a master with this knowledge.
