Not at all! A very progressive rock band. BUT, if you weren't there then that makes a difference. They broke the mold with rock as did King Crimson -- although differently. Recordings? Well, some not so good but hits the heart of the early 70's rock fan.
Anyone who thinks The Moody Blues were "a very weak band" probably also believes Bob Dylan is the greatest vocalist of all time.
Also, listen to their early, early stuff like Go Now and ask if there has ever been a band that has undergone such a drastic change in style and sound? They were kind of on the weak side of the British Invasion. Then Hayward and Lodge came aboard and taught everyone about LSD, Buddhism, and the like.
I'd have to jump on that old bandwagon that no one has had as many changes in their lifetime as the band known as King Crimson ...
Then again, there is the Fleetwood Mac Blues band, that went through lots of changes on the way to Buckingham Nicks resurgence ...
Moody Blues albums have this air of cohesiveness around them. It's not easy to pick one track on any of their albums and start from their; you really do have to go from Side A to Side B, and from start to finish.
I like To Our Children's Children's Children and In Search of the Lost Chord. I'm not the world's biggest fan, but to those of you who say that they're terrible, try expanding your tastes.
Their early stuff, though...don't even get me started on that! I found an imported "Beginnings" album of some of their first-album material, and I haven't been able to listen to the whole thing. Thoroughly boring.
