Maynard! Maynard! Maynard!— The legions of Tool fans (who can ignore the fact that the lead singer’s name has "nard" in it) should be stoked to mark March 23 on their calendars. Yes, Tool is coming, nards in tow. Buy tickets Saturday, Jan. 27, at 10 a.m. A big $49.50 will get you space on the floor and $39.50 will get you a spot in those crappy stadium seats I’m always in. And, as it always is at Tingley Coliseum, expect tons of mismanaged echo in your concert experience.
