Wes is an amazing guitarist. Sometimes he can get a little too overboard with effects pedals IMO but really is underrated. I never really understood how Limp suddenly became such a joke on such a level. So so so many people were into LB sending them to arena status, and then it seemed like overnight it became "the cool thing" to hate on them. I know Fred D ran his mouth and could act a fool quite a bit but the popularity of that band pulled such a 180. Anyhoo, a song pops up on shuffle every now and then and I have no problem rocking along in my car.
Back on track, Filter had a another gust of wind in its sails with their last album. I know a new CD is on the way and a big opportunity to keep that push going. I can't imagine he'd risk even a piece of his dedication to do an AoA reunion let alone fill in as the new singer of STP. And the DeLeos & Kretz would be crazy to try and recruit another lead singer with commitment to another band, especially RP in which Filter is his absolute baby.
I could see him guesting on something for them. Or yes I do remember him saying he wouldn't be against revisiting AoA but I honestly would envision a relationship more similar to Weiland and Art of Anarchy, than of a touring/evolving relationship with the rest of the band.
I think STP can really only save face by just trying to find someone rather unknown, who can do some sort of justice to the STP catalogue, and who is 100% dedicated. But move forward and create new music, and support it....not a handful of songs which you only embrace one. But with that should also come the recognition that they're not a big marquee name anymore. Get to touring with some other reasonably comparable artists and win people back. Stop going around touring as an unproven group and charging $60+
This band shouldn't expect to be the next Van Halen, it should expect to be the next Live.
