Most musicians improve their musicianship, technique, and creativity as they get older.
The Black Album is the obvious turning point where Metallica stopped doing all of the above. They stopped making music and started listening to their manager (can't remember his name). HE was the one who suggested to James that he put that anoying growl on the end of every phrase (eg. Entersandman: "ennnterrrr night-yahgh") which got progressivly worse with the new albums.
Don't get me wrong, the black album is still great. "My Friend of Misery" is still one of my favorite songs. I have no quips with the ballad ("Unforgiven"), but when a band starts writing sequels to their own songs and sequels to their own albums someone has to pull the plug.
I want the 7-10 minute anthem to come back. Thats what its all about. Granted radio stations won't want to play it as much, but I know around here "Master of Puppets", "One", and "Fade to Black" get more play than the new album. . . . Tool gets plenty of airplay with their long songs.
I own a Flotsam and Jetsam Album and it is about as far from St. Anger as the Everly Bros. Don't blame Jason. Its all Lars and James trying to conform to what their managers said the public wanted.
It is unfortunate that the teenagers of the time don't know good music. I feel like I'm getting old, not being able to listen to today's rock. But everyone I talk to is in agreement that it SUCKS. I'm just waiting for the day that I hear Metallica's early work on Classic rock stations.
