From what I have heard (but I haven't seen ...Later yet, I'll record it Friday night), KOL supported Carla Bruni, not Metallica.
TBH I am probably with the majority of old scholl Metallica fans, in that I like their stuff up to the black album, then they went way off track (Metallica doing country? gimme a break!). I do however have a copy of Load and Re-load. Listened to St Anger once and thought that they were not really going in a direction I could appreciate so left it. May have to check out the new stuff, maybe Jason Newkid was spoiling it for them? The best album they ever did wasn't even an official one, but well worth finding if you can, it's "Sanatorium, live from Nassau Coliseum", feturing the best bass solo I have ever heard, i.e. Orion.
