What I heard and saw at the show in Los Angeles was a group of very talented, highly experienced musicians playing some great rock and roll. The songs were well-crafted and the band is still taking improvisational risks that can either get you there or not. At the Forum show, I was spell-bound most of the time. The only real notable exception was Scarlet > Fire, which was a matter of personal taste - I've just heard too many versions of those songs where Jerry's solos combine with the band's groove to achieve lift-off.
On that night, 05-09-09, the band was focused, funky, soulful and they rocked. I would say without hesitation that the LA show rivaled any of the shows I've seen (well over a hundred) since 1977 when I saw my first. In the last fourteen years I've seen dozens of shows - Phil & friends, Ratdog, The Other Ones, Rhythm Devils, etc... that were quite enjoyable, but The Dead 2009 really hit the spot!
This was the only show I saw on this tour and I haven't really listened to recordings of any other 2009 shows. So I don't know if 5-09 was the rule or the exception. What I can say is I hope they tour more!
Your mileage may vary ....
