A bunch of misconceptions here I'd like to straighten out:
1. I'M over 30 and I listen to Limp Bizkit.
2. Albums used to come out every SIX MONTHS! Look at the back of KISS's "Smashes, Trashes and Greatest Hits" and it has the release dates for their early records and until they did their solo albums, they dropped new product every six months.
The reason releases have gotten so far apart is that the record companies have such extended marketing strategies. Release a single and video, work it for 3-4 months until it starts slipping off the charts, repeat. If a band can pull more than 3 singles, then it may be over a year before the label lets the band into the studio again. Major label releases can take from three months to OVER A YEAR to record, mix, do art, etc. It adds up.
That's why Prince was so unhappy with Warner Brothers. He wanted to release tons of stuff, all the time, and WB just didn't know how to market to flood. (This is not to say it would've all been good.)
3. The Pixies dropped an album a year for five years straight before breaking up. Their last one was their best, though none of their records rated worse than "really good" in my book.
4. "Significant Other" is THE LB album to have. "Three Dollar Bill, Y'all" was the band finding it's legs and "Chocolate Starfish..." is the Fred revealing that he doesn't have more than a few tricks in his bag and we've heard them already. Some of the tracks RAWK!!! but overall, it shows that there's not a lot of there there, ya know?
5. I am a musician (see sig) and while I'm wrapping up our new CD, I have at least TWO more albums of solid material written and demoed and I'm still writing. Bands always say, "We wrote 95 songs and recorded 32 of them and then picked the best 12.", and the record has only a few good tunes at best. I like to think that I only write a few good songs as opposed to tons of crap.
Hell...look at the Beatles. They wrote great, TIMELESS music through their entire run. They're an exception, of course, but some bands can crank out lots of good tunes over many years. Limp Bizkit ain't one of them.
