I had almost nineteen years to discover the University's annual Halloween Concert -- nineteen years of raising children (and counting). I meant to go every year, really I did. From the description it looked pretty interesting. But to make it to the 7 PM performance you have to get dinner on the table early; and the 9 PM performance is too late for pathetic me, so we somehow missed it every year.
Well this weekend we went, and it's not to be missed. Make sure you go next year. Take your kids, and wear your costumes. It's raucous, it's wild, it's massively attended (to the point of fire code violations), and the music is great.
