I would guess they gathered the singles more than anything else. I mean the guy had around 12 songs released as singles before his first album. It was just a different time, from what most on this list seem to be. In comparison, a huge disciple of his, Jimmy Page, wasn’t all that big on releasing singles period. That is why it took so long to get Zeppelin on iTunes. He thought the albums should only be sold as a whole.
I’m not saying that Link Wray isn’t hugely influential. Just that I can see the reasoning behind him not having an album on the list.
Quite true .. in fact, as you well know, Zepp's biggest hit was never a single at all ... "Stairway To Heaven" was never released as a single, one had to buy the entire Zepp IV in order to get it. Not a bad deal since that album overall is quite classic.
Not a lot of radio play, but he sold albums like crazy over there because he was an “American bad boy”, in spite of the fact that he was really pretty clean-cut for the times, and because of that sound.
The American music business people just thought his guitar was “too raunchy”.
