I have seen dozens of shows at Gammage over the years. I love theater and this is a great venue to see a national touring production of a hit show. Gammage is architecturally a beautiful building. Frank Lloyd Wright is the man! One thing I have noticed about this particular auditorium is there is often some type of acoustic problem and there have been shows that have had some type of sound issue. Two that come to mind were My Fair Lady and Jersey Boys-both were great shows but there were some technical difficulties involving sound.
Make sure you use the bathroom before you get there if possible as there is always an enormous line and the restrooms are quite small compared to the capacity of the theater.
