On the poster the actual Album from Tad “God´s Balls” is shown (in the right corner underneath), but still not the brand new Nirvana debut-album “Bleach”. I suppose reason is, that the poster was printed long time before the release of their Album. On that tour Nirvana played in several German clubs. Are you one of the few happy people who had the chance to see Nirvana in a small audience in this early times? Some of these concerts had more or less than a hundred spectators. Please never forget Kurt Cobain and never forget: This music is “only for vegetarians”!
