When I hear Sweet, I think about the song "Hurricane" he teased/partial'd back with Tim a couple times in '09. Cool little riff, kind of a laid-back island vibe, with lyrics that seemed to be suggest a nostalgic reflection on love. Not new territory by any means, but both are efforts that have beauty in their simplicity as opposed to the spastic 5 minute seizure that is Blackjack. I'd much prefer to hear a quiet little tune like Sweet/Hurricane/Butterfly in the E1 slot rather than Some Devil/Sister or for the 20th time. Hell, I'd be happy to hear E1 Dive In again, it takes on a darker tone that fits the vibe of the song much better than how it's played full band currently. (Apparently they gave up on developing an instrumental section at the end of the song after two attempts in '09.)
For whatever reason Dave has gotten horrible at recognizing which ideas to explore further and which one's to axe, and as refreshing as it is to see Dave finally toying with the '06 songs again, it's pretty obvious that some of those should not have been resuscitated. They clearly have not aged well in their current form, and they show no signs of receiving any kind of overhaul. Dave was obviously not satisfied with the way they sounded 5 years ago or he would have kept playing them. Why bring them back now if they have no intention of improving them at all? To please the diehards?
There is no way they are that out of touch with the fanbase. If the band is going to cave into fan pressure to bring back obscure live releases and rarities, why bring back the shitty ones? Yes Captain and Raven have returned, but I think the band knows we'd all prefer to hear something in the vein of YNK than Kill the King and Can't Stop. In the spirit of laziness I suppose its just easier to play the shit from '06 rather than digging a little deeper and pushing a little harder to nail a complex song.
