I'm not sure if I dropped some knowledge about this subject yet to you guys, so excuse me if you're heard this before....
Re-alt is a term that stands for, becoming alternative again. We have seen many instances where someone has re-alted themselves. But I think the best case study of this phenomenon is the band
Nada Surf.
Case point #1: Nada Surf releases High/Low (1996). "Popular" becomes a mega hit, foreseeing the possibility of being a one-hit wonder! It's placed in the MTV buzz bin. INSTANTLY MAIN!
Case point #2: Now that they are MAIN, they are completely abandoned by the ALTS. And therefore totally not cool.
These guys are in serious need of a re-ALT! And this is how they did it...
Step 1: Realize that you're MAIN. Recognizing that there is a problem its the hardest yet most important part of a re-ALT.
Step 2: Release at least 3 albums of complete garbage. (IE, The Proximity Effect, Let Go, The Weight is a Gift)
Step 3: Put out a fresh new record on a respectable indie label. (IE, Barsuk)
Step 4: Relocate to an "ALT" neighborhood. (IE, Brooklyn) -I'm not sure of their original location, so I might be wrong about this, but there is nothing more ALT than Brooklyn.

And so now that the MAINS have completely forgotten about your one hit from 1996, you can re-emerge on the ALT scene. Because the fact that you were ALT-to-MAIN-back to ALT, is cool with ALTs. Great work guys!
Now the true test...is their new record good or just a feeble attempt at a re-ALT????
Are dreads the new crazy hair for White Indie-rock dudes????
...so many questions left unanswered, I feel like this is an episode of LOST!
