I’m always amazed at how many guitarists achieve a very high level of proficiency in lead guitar playing fairly early i their lives, but then make little or no effort to continue to grow as lead guitarists.
I reall have to think to come up with exceptions to this, so here are a few guys who I think are or were, exceptions:
Glenn Tipton and K.K.Downing of Judas Priest - In the 1970’s they were very much blues based heavy metal guitarists with a good technique for the standards of the time although they weren’t considered to be on the level of greats of that era such as Ritchie Blackmore, Michael Schenker, or Uli Jon Roth. However, they gradually showed an increase in their technical abilities,with early 80s albums such as Screaming For Vengeance and Defenders Of the Faith. Then by the early 90s, with the Painkiller album they had made dramatic improvements in their technical abilities with faster, clean alternate picking and even sweep picked arpeggios! That kind of constant drive to improve is rare for some reason and I commend them for having it.
Criss Oliva of Savatage - Criss made significant changes in his lead playing from the Savage debut album “Sirens” to his last album he recorded with Savage - “Edge Of Thorns.” I always liked his playing very much. I thought his playing on “Sirens” was great - so aggressive and intense! As time went by you could here that he was moving away from being primarily a blues scale based player to a player who utilized diatonic scales more and more. While his picking continued to remain impressive, he greatly refined his legato technique, his phrasing and his use of tapping.
Randy Rhoads - I haven’t heard much of his playing with Quiet Riot and what I have heard was many years ago so I don’t clearly remember how it sounded but he clearly made some leaps and bounds in his playing from his time in Quiet Riot to his playing with Ozzy. As great as he had become by the time he had become Ozzy’s guitarist, he wasn’t content to just rest on hs laurels. Instead, when he was on tour, after checking into a hotel room, he would look in the yellow pages for classical guitar teachers and take a lesson from a classical guitar teacher in every town he could!
The list of guitarists who stopped trying to grow as players after a relatively early point in their lives is too long to do more than just scratch the surface but a few guys who are notorious for stopping improving their lead guitar abilities very early are:
Yngwie
Kirk Hammett
Dave Mustaine
Marty Friedman
Michael Angelo batio
Vinnie Moore
Warren DiMartini
George Lynch
Ritchie Blackmore
Iron maiden’s guitarists
Matthias Jabs of The Scorpions
Joe Satriani? (I haven’t followed his later albums closely enough to be sure)
Tony Iommi (after becoming accustomed to the plastic fingertips he constructed for himself as prosthetic devices).
Vivian Campbell
Obviously these are my opinions. If you have different opinions on a few of these guys, or many of them, just state your reasons for believing I’m wrong. All opinions are welcome!
