I tried going through the RIAA’s “Diamond” certified albums and seeing which ones might be regarded as having “great” guitar. I tried to identify a) Albums where guitar has a significant role, regardless any value judgment about it, b) Albums where the guitar playing could arguably be classified as having some “shred” qualities to it, c) Albums where guitarists today generally recognize artistic importance or significance to the guitar playing. Note that an album could satisfy b without satistfying c, and vice versa, and b and c are both subjective and fodder for debate.
Here’s the RIAA link I used as a source:
https://www.riaa.com/gold-platinum/?tab_active=top_tallies&ttt=DA#search_section
Based on my first cut, here are the diamond albums that I think satisfied all of a, b, and c:
Journey, Greatest Hits
Metallica, Metallica
Van Halen, Van Halen
Van Halen, 1984
Albums that satify “shred”, but are iffier on “importance/influence”:
Bon Jovi, Slippery When Wet
Def Leppard, Hysteria
Def Leppard, Pyromania
Albums that satisfy “importance/influence” but are iffier on “shred” (note that this includes compilations and “best of” albums even when it’s arguable that the primary influence of the content predates the compilation (e.g. The Beatles, 1)):
Guns N’ Roses, Appetite for Destruction
Led Zeppelin, Led Zeppelin II
Led Zeppelin, Houses of the Holy
Led Zeppelin, Led Zeppelin
Led Zeppelin, Led Zeppelin IV
Led Zeppelin, Physical Graffiti
Pink Floyd, Dark Side of the Moon
Pink Floyd, The Wall
Prince and the Revolution, Purple Rain Soundtrack
AC/DC, Back in Black
Bob Marley and the Wailers, Legend
Creedence Clearwater Revival, Chronicle: 20 Greatest Hits
Doobie Brothers, Best of the Doobies
Eagles, Greatest Hits Volume II
Eagles, Eagles/Their Greatest Hits 1971 - 1975
Eagles, Hotel California
Eric Clapton, Unplugged
Green Day, Dookie
James Taylor, James Taylor’s Greatest Hits
Michael Jackson, Thriller
Nirvana, Nevermind
Simon and Garfunkel, Simon and Garfunkel’s Greatest Hits
The Beatles, Sgt. Pepper’s Lonely Hearts Club Band
The Beatles, The Beatles
The Beatles, The Beatles 1962 - 1966
The Beatles, Abbey Road
The Beatles, 1
The Beatles, 1967 - 1970
The Doors, The Best of The Doors
The Rolling Stones, Hot Rocks
U2, The Joshua Tree
ZZ Top, Eliminator
Albums I’d give credit for at least one of “b” or “c”, but I think would be “controversial” inclusions:
Boston, Boston
Santana, Supernatural
Creed, Human Clay
Aerosmith, Aerosmith’s Greatest Hits
Kid Rock, Devil Without a Cause
Smashing Pumpkins, Mellon Collie and the Infinite Sadness
Perhaps the most interesting is Santana. Carlos Santana has been hugely influential when you look at his entire career. By the standards of the mid-1970’s, we might have classified him as a “shredder”, but by contemporary standards he fits more in the same kind of category as Led Zeppelin. And while Supernatural was a huge commercial success, you could argue that it’s not his most “adventurous” guitar playing. On the flipside you could describe Supernatural as a triumph of maturity and restraint over flash for the sake of flash, by an artist at the peak of his powers.
Edit: As part of this exercise, I learned about the existence of a Diamond record for country act “Florida Georgia Line”, who I had never heard of previously. After watching the video for their biggest single, I did a little more reading and was dismayed to learn that they weren’t, as I assumed, a genre parody act in the same vein as The Darkness. Apparently these guys are the unironic “Nickelback of Country”. Incidentally, Nickelback also has a Diamond record (“All the Right Reasons”). While Nickelback is unapologetically calculated, I find that some of their songs at least have catchy hooks; I’m not sure that’s the case for Florida Georgia Line, but I really don’t feel motivated to make the effort to find out.
The most prominent country act in the “Diamond” list is Garth Brooks, with 7 albums. While Brooks himself is hugely influential as a performer, I don’t think even country artists would describe the actual guitar playing on his albums as being particularly influential. You could argue that Brad Paisley is making history in country guitar right now, but he wasn’t included in my exercise because he doesn’t have a diamond record yet.
