Is there any greater opening to a first song on a first album by a legendary band? The opening notes of Good Times Bad Times just ROCK. This is a band that kicked ass from their first moment. The Led Zep sound was there from that first album: Plant's stellar vocals, Page's amazing guitar, JPJ rounding out the sound on bass and keys, and Bonham's thunder. It's also interesting to listen to how they changed the songs they covered (often without attribution...this album includes at least two future lawsuits - Jake Holmes suing over Dazed and Confused and Willie Dixon suing over You Shook Me and I Can't Quit You Babe). Babe I'm Gonna Leave You is a great example of how they took an existing song and made it their own. It was written by Anne Bredon and previously performed by Joan Baez (listen to her 1962 live album). It's a completely different song when Baez sings it and a good example of how a cover that significantly reinterprets another song can practically be considered a new song. In contrast, take a listen to the evolution of Dazed and Confused. The original Jake Holmes version (1967) has different lyrics (except the key "dazed and confused" but even that's slightly different) and a mostly different tune except for the key chromatic bass descent. BUT, the tune Led Zep uses is identical to how the Yardbirds covered it in 1968. To be fair, that was with Jimmy Page...in fact, Led Zep was originally supposed to be "The New Yardbirds" so were they really "stealing" it from the Yardbirds? But anyway, the Led Zep version is nearly identical to the Yardbirds' version (right down to Jimmy doing the violin bow thing) but the Yardbirds used Holmes' lyrics. How did the Yardbirds come to start playing it? Holmes opened for them in 1967. According to Wikipedia, Holmes said, "That was the infamous moment of my life when 'Dazed and Confused' fell in to the loving arms and hands of Jimmy Page." It wasn't until 2012 that Holmes got writing credit from Led Zeppelin. So, were Led Zeppelin inveterate music thieves? Well, yeah. But their originals are amazing (standouts on this album: Communication Breakdown, Good Times Bad Times) and the covered songs are almost always taken to the next level - just a shame they didn't give credit where credit was due (until sued). Either way, over 50 years later their sound remains unique while setting the standard for every hard rock band to follow. And they did it right from their first album. 5 stars.
