As far as legacy, STP is in a unique position. Before, they were trying to separate themselves from Scott to limit the damage to the band's legacy during the reunion. But now, they're in a unique position to repair the damage Scott did to his own legacy. They are sitting on a gold mine of Weiland's best performances, and even recordings he did at his peak.
That's why I think they need to drop the STP name, or at the very least bring back "Featuring" when they find a new singer. But all things considered, I'd rather anything released under the STP name to be a representation of Scott at his peak.
I don't know what any legal issue there would be with Weiland's estate or with Atlantic, but I'd like to see STP do the following:
1. Reissues of the classic 5 albums.
2. Release the very best of STP classic live footage. At the very least, a release the Vegas HOB show.
3. One final 'Thank You' album, composed entirely of outtakes and b-sides from the 99-02 sessions, produced by Brendan O'Brien.
4. Only two more STP shows, ever. One fundraiser for Scott's relatives, the other when and if they get into the R&R Hall of Fame.
