If I can add something to this thread (which is not gonna help much for a choice, though
) there was really something "special" in Köln (where I was)... a kind of "1st gig since quite long" energy, new disposition for the gear, "old/new" setlists, an amazing Peach Tree / Spoonman / Cherry Pie / Rowla serie, etc... imo Köln is definitely a must have...
