Although this solo-career retrospective ignores Robert Plant's fine first album (not to mention 1983's incandescent "In the Mood"), Sixty Six makes a convincing case that Plant's artistry didn't end with Led Zeppelin. Besides unveiling four pre-Zep rarities — including 1967 covers of "Hey Joe" and "For What It's Worth" — the set finds Plant's expressive voice in fine form on folk-rock hymns such as "Darkness, Darkness" or the "Kashmir" update "Calling to You." If only Plant could have gotten over his disdain for his early-Eighties work, Sixty Six would have been definitive.

“Is It True”

As the British Invasion reached its peak in 1964, Brenda Lee went from Nashville to London to record one of her hardest-rocking hits, her perky vocal backed by a stuttering, squalling guitar. That guitar was played by session musician Jimmy Page, yet to skyrocket to fame with first the Yardbirds and then Led Zeppelin. "She said to me, 'I've come here to make a record with the British sound,'" remembered producer Mickie Most. "She felt she wouldn't get the same sound in Nashville because they're only just catching up on the British beat group sound of about six months ago."
