The sound is perfect. John Paul Jones welcomes the congregation on theorgan, Jimmy Page’s guitar plucking is sublime, Bonzo’s unflappable,and just as Robert Plant lays into the chorus of “Your Time Is GonnaCome,” I realize: This is as good as it’s gonna get—my old LP, my”new” speakers, my turntable, and my living room. If I’m gonna get theLed out, there’s no better place to do it than in my own house. Yetthis week, there’s a pair of bills that beg to differ. There’s thetribute act, No Quarter (at the Tractor Tavern), which was recentlysnubbed by Bonnaroo in favor of Lez Zeppelin, the all-female fakers.The other is a rock band and orchestra performing “The Music of LedZeppelin” at the Paramount. If it’s anything like that mid-’90s set Isaw at the same venue, featuring the Seattle Symphony and a rock band(Soundgarden’s Matt Cameron, Slash, half of Queensryche, etc.)performing grunge staples, it’ll be well worth it.
