I'm about 1/2 way thru "When Giants Walked the Earth - A Biography of Led Zeppelin" (2009) by Mick Wall. It's been a trip (so far) to the late 50s, early mid & late 60s & into the 70s & thru the first 3 Led Zepp albums, their live concerts, recording sessions & after concert partying. Major flashbacks for this ole guy who's been a fan since I heard "Led Zeppelin", their eponymous first album. Totally enjoyable. So, what're the rest of you hearth-heads reading?
