In Through The Out Door was the last 'good' Zeppelin album. The use of synthesizers was a big deal back in the day, took a lot of people a while to warm up to that record...but it's a masterpiece compared to the limp Coda. Credit to Jimmy for throwing the bits and bobs together to make an album of any kind, but it will never be one of their best. It's a matter of time for me, the time I have left I will listen to the music I love the most, and leave the mediocre stuff on the shelves. And of course my opinions vary from other folks, nothing wrong with that either.
Think I'll play II a little later in fact.
