Bracing myself for the hate but...
I genuinely don't think the Deleo's have really released any interesting music since 2006's 'Army of Anyone'. There may be one or two exceptions but generally I felt like S/T and High Rise were rather generic and showed the Deleo's in 'play it safe mode'.
I'm not trying to take away from their obvious talent, those guys have written some of my favourite songs of all time but I'd like to see them get a little more creative/experiment on the next record they put out... Again, just my opinion.
I think S/T they played it way too safe, but there were some legitimately interesting instrumental moments in High Rise... It's really unfortunate that wasn't a full album.
But if we're honest, everyone played it safe after the reunion. S/T and High Rise weren't as dynamic as AoA, Talk Show, or the original five STP records... But with Scott, he pretty much mailed in S/T and Art of Anarchy, and Blaster was fairly derivative of classic rock. Not to say his work on those albums is bad, just that he wasn't reinventing the wheel anymore like he did on pretty much every album he worked on beforehand.
The best STP related album to come out after the reunion was 'Happy', and most of that music was actually from the SLDD-Velvet Revolver eras.
This is sort of why I want to see the DeLeo's take the outtakes from the 99-02 sessions and release it as a 'lost album' of sorts. Whatever material didn't make it onto an album from those sessions is bound to be better than what was released on S/T, and probably whatever will be released coming forward, unless the DeLeo's dig deep and do something on the level of AoA again.
If they release that material as a Coda album, then come what may with the STP name and legacy, at least the original line-up will have a more fitting farewell than S/T.
