Hi, long time lurker here, but I agree with all of this. Some people let themselves be blinded by nostalgia. We're lucky that LP even play any of their old songs, that they even power through the songs they've played hundreds of times and know like the back of their bloody hand. A lot of artists just ignore their old albums, see: Smashing Pumpkins who refuse to play most of their discography with the exception of a few new albums.
LP try to satisfy the old and the new - not many bands can say that.
