I love Stage AE. It's the perfect size venue. They are big enough to get some awesome bands but they are small enough that you feel engaged and a part of the music. You don't need a pair of binoculars to see the band.
I also like that you can get a 24oz beer for $7.25, which is pretty good for a concert venue...shoot that's good for a bar on the north shore. They have a few beers on tap, some premium beers on tap for outside concerts, and bottled beers.
I find that the sound quality is better outside than it is inside. I feel it's really an outdoor venue that also does inside shows.
overall this is a great place to go see a show.
