I've only listened to Disc 1 of the new album so far but it is beyond phenomenal. I've seen Page and Plant, and they were amazing, but listening to this music makes me sad that Bonham died just after I was born. Without him, no Led Zeppelin, period.
I'd liked them for a long time, and I became a major fan just after high school. They are in my top five bands, and the only music that gets into my top five is music I consider beautiful, because that's my top criteria. Led Zeppelin's music is also fun, raucous, scary, insane, and a host of other things, but they created such beautiful sounds. Both when they were being light, and when they were being heavy--what other band has ever had such a perfect name? It's the most visceral music ever created. I'm not certain I would call them my favourite band, but I tend to think that they were the greatest band of all time, and that we will not see their like again.
